PITIA stands for principal, interest, taxes, insurance and association dues: the full monthly cost of carrying a mortgaged property. The formula is PITIA = principal and interest + property taxes + insurance + HOA dues, each counted for one month.
It matters most on rental loans. A DSCR lender divides the property's monthly rent by its PITIA to get the debt service coverage ratio, and counts the cash you must keep in reserve in months of it. Get the taxes, insurance or dues wrong and the loan can change as much as if the rate had moved.
What does each letter in PITIA cover?
| Letter | What it is | Sample house, a month | Where the figure comes from |
|---|---|---|---|
| P | Principal: the part of the payment that reduces the loan | $222.64 in the first month | The loan's amortization schedule |
| I | Interest: the lender's charge on the balance | $1,875.00 in the first month | The rate and the balance |
| T | Property taxes | $400.00 | The county's records, at the price you pay |
| I | Insurance on the property | $150.00 | A quote for a landlord policy |
| A | Association dues: HOA or condo fees | $50.00 | The association's budget |
| PITIA | $2,697.64 |
Principal and interest together are a fixed $2,097.64 a month on a fixed-rate loan; only the split between them changes, with more going to principal each month. Taxes, insurance and dues change every year, which is why a PITIA worked out at application can be wrong a year later.
How do you calculate PITIA?
PITIA on the sample house, long-term and short-term
The example deal used across these guides is a $400,000 single-family house with 25% down, set out in full in how to analyze a rental property. The rate is an example, not a quote.
- Principal and interest. A $300,000 loan at an example 7.5% fixed over 30 years is $2,097.64 a month.
- Taxes. $4,800 a year ÷ 12 = $400.00.
- Insurance. A landlord policy at $1,800 a year is $150.00 a month. Run as a short-term rental, it needs a policy written for paying guests, assumed here at $2,400 a year, or $200.00.
- Association dues. $50.00 a month.
| Long-term rental | Short-term rental | |
|---|---|---|
| Principal and interest | $2,097.64 | $2,097.64 |
| Property taxes | $400.00 | $400.00 |
| Insurance | $150.00 | $200.00 |
| HOA dues | $50.00 | $50.00 |
| PITIA | $2,697.64 | $2,747.64 |
| PITI (without the dues) | $2,647.64 | $2,697.64 |
The same house has two PITIAs because the insurance differs with the way it is rented. Short-term rental insurance explains why that policy costs more.
PITI vs PITIA
PITI is principal, interest, taxes and insurance, the four parts of a monthly mortgage payment as consumer guides describe it. PITIA adds the association dues. Fannie Mae's guide and most investor lenders use PITIA, because dues are a fixed monthly obligation the property must carry whether or not they pass through the loan.
That is also the practical difference. If your loan has an escrow account, the servicer collects principal, interest and a twelfth of the taxes and insurance each month, then pays those bills for you. HOA dues usually go straight to the association. So on the sample house, the servicer's bill would be $2,647.64 (PITI), you would pay the $50 of dues separately, and the lender would underwrite all $2,697.64. Without escrow, the servicer bills only the $2,097.64 of principal and interest, and you pay the tax and insurance bills yourself.
What else do lenders count in the payment?
Fannie Mae's definition of the monthly housing expense is wider than five letters. Where the property has them, it adds:
- flood insurance, and mortgage insurance on a loan that carries it;
- special assessments an association has levied;
- ground rent, where the land is leased rather than owned;
- co-op fees, and the payment on any second loan secured by the same property.
Investor lenders work the same way in practice: if a cost must be paid every month to keep the property and the loan in good standing, expect it in the payment. Utilities billed to the unit, repairs and management are not part of PITIA.
How does PITIA feed the DSCR?
On a DSCR loan, DSCR = monthly rent ÷ PITIA. The lender counts the lease or the appraiser's market rent for a long-term rental, and history or a discounted projection for a short-term one. How to calculate DSCR covers how each kind of rent is counted.
On the sample house as a long-term rental: $3,000 ÷ $2,697.64 = 1.11. Most programs want 1.00 or more, and many price best from about 1.25. Two ways to read the same numbers:
- The rent needed for a 1.25 ratio is 1.25 × $2,697.64 = $3,372.05.
- The most PITIA that $3,000 of rent can carry at 1.25 is $3,000 ÷ 1.25 = $2,400.
As a short-term rental, a lender counting 80% of the projected $72,000 a year would use $4,800 a month: $4,800 ÷ $2,747.64 = 1.75.
Because every part of PITIA sits in the denominator, small changes move the ratio:
| Change to the long-term version | PITIA | DSCR on $3,000 |
|---|---|---|
| None (the base case) | $2,697.64 | 1.11 |
| Insurance $100 a month higher | $2,797.64 | 1.07 |
| No HOA dues | $2,647.64 | 1.13 |
| Loan of $280,000 (70% of the price) | $2,557.80 | 1.17 |
| Loan of $320,000 (80% of the price) | $2,837.49 | 1.06 |
| Interest-only on $300,000 | $2,475.00 | 1.21 |
The loan-to-value ratio sets the principal and interest line, which is why borrowing less is the quickest way to lift a ratio that falls short.
PITIA on a conventional loan
A conventional loan for a rental uses PITIA differently: it qualifies you on your income, and the rental enters your debt-to-income ratio. On a purchase, Fannie Mae's guide counts 75% of the gross rent and subtracts the property's PITIA. For the sample house that is 75% of $3,000, or $2,250, minus $2,697.64: a shortfall of $447.64 a month, which is added to your monthly debts. The same house that passes a DSCR lender at 1.11 adds a cost to your personal ratios at a conventional one, which is one reason investors with several rentals move to DSCR loans.
ITIA: the interest-only version
On an interest-only loan, many lenders work out coverage on ITIA: interest, taxes, insurance and association dues. With no principal in the payment, the sample house's interest-only payment is $300,000 × 7.5% ÷ 12 = $1,875.00, so ITIA is $1,875.00 + $400.00 + $150.00 + $50.00 = $2,475.00, and the ratio rises from 1.11 to 1.21. The loan does not shrink during the interest-only years, and the payment jumps when they end, so check how the lender treats that later payment.
PITIA and reserves
Lenders also measure the cash you must have left after closing in months of PITIA. On a conventional loan for an investment property, Fannie Mae's automated underwriting asks for six months. DSCR lenders commonly ask for 2 to 12 months, often 6, more for a first-time investor or a ratio below 1.00. Six months of the sample house's PITIA is 6 × $2,697.64 = $16,185.84. DSCR loan requirements has the rest of the checklist.
What PITIA leaves out
PITIA is the lender's measure of whether the rent carries the debt. It is not your cost of owning the property. It leaves out vacancy, management, repairs, the capital reserve for roofs and systems, utilities you pay and every short-term rental running cost. On the sample house, a 1.11 ratio sits beside a cash flow of minus $375.64 a month once those costs are paid. Analyze the deal on its full costs, and treat the lender's ratio as a test the deal has to pass, not proof that it works.
Getting PITIA right before you apply
- Insurance: get a quote, and check the flood zone, as soon as you have an accepted offer. In storm and wildfire country this line moves the ratio most.
- Taxes: use the tax on the price you will pay. Many places reassess after a sale, so the seller's bill can understate it.
- Dues: read the association's budget and minutes for planned increases and special assessments, and its rules on rentals.
- Rate: price principal and interest at a rate you can actually get, with the points you would actually pay.

Frequently asked questions
What does PITIA stand for?
PITIA stands for principal, interest, taxes, insurance and association dues. Together they are the full monthly payment a lender considers when it underwrites a mortgage. On rental loans, especially DSCR loans, lenders divide the rent by PITIA to see whether the property can carry its own debt, and measure required reserves in months of it.
Is PITIA the same as my monthly mortgage payment?
Not always. The servicer's bill usually covers principal and interest, plus taxes and insurance if you have an escrow account. HOA dues are normally paid to the association directly. PITIA counts all of them, because the lender wants to know the full monthly cost of keeping the property, whoever each payment goes to.
Does PITIA include HOA dues and flood insurance?
Yes. The A is association dues, including condo fees, and lenders add special assessments the association has levied. Flood insurance counts within the insurance line when the property needs it, along with any wind or hurricane policy. Each one raises PITIA and lowers the coverage ratio, so confirm them before you apply.
What DSCR do lenders want on PITIA?
Most DSCR programs want the rent to cover PITIA at least once, a ratio of 1.00, and many price their best rates from about 1.25. Some programs accept ratios below 1.00, or no ratio at all, in exchange for a larger down payment, a higher credit score, more reserves and a higher rate. Requirements vary by lender and change often.
How many months of PITIA do I need in reserves?
It depends on the loan. Fannie Mae's automated underwriting asks for six months of PITIA on an investment property purchase, and more when you finance other properties. DSCR lenders commonly ask for 2 to 12 months, often 6, with more for first-time investors, large loans or coverage below 1.00.
