What reserves are
Reserves are liquid funds you hold after you have paid the down payment and the closing costs. Lenders usually count them in months of PITIA. If your full monthly payment is $2,400 and the program wants six months, you need $14,400 left in an eligible account after closing.
The money stays yours. The lender only needs to see that it exists at the time of underwriting.
Why lenders ask
A rental loan is repaid by a tenant. Tenants move out, furnaces fail, and a unit can sit empty for a month or two. Reserves are the lender's evidence that a gap in rent will not immediately put the loan in trouble. For you they serve the same purpose, which is why experienced investors usually hold more than the minimum.
What usually counts
Requirements vary by program, but the pattern is consistent.
- Checking and savings balances
- Brokerage accounts, often counted at a discount to current value
- Retirement accounts, usually at a steeper discount and sometimes only if accessible
- Funds from the cash-out proceeds of the same loan, on some programs
- Not counted: the down payment itself, or money you have already spent at closing
How to plan around them
Ask for the reserve requirement at the quote stage, not at underwriting. It changes the amount of cash a deal needs, and it is the most common reason an investor has to delay a closing.
If reserves are tight, a smaller loan or a slightly lower purchase price can help twice. It lowers both the cash you need up front and the monthly payment the reserves are measured against.
