Using one rental to buy the next? Count both payments.

What a lower headline rate means for a two-property plan

On November 5, 2026, Freddie Mac reported that its weekly average for a 30-year fixed mortgage eased from 7.24% to 7.18%. The survey tracks owner-occupied purchase mortgages. If you plan to borrow against a rental to buy another one, ask for separate financing estimates for the two properties. Even when market rates ease, replacing an existing loan with a larger balance can raise the monthly payment.

If you already have a rental in mind, start your application with the addresses of both properties. Still looking? Check loan options to get a sense of what information to gather before making an offer.

Work backward from the cash you need at closing

Suppose a purchase calls for $50,000 down and $6,000 in closing costs. You have $16,000 available for the purchase after setting aside the cash you want to keep for repairs and vacancies. That leaves $40,000 to find. Ask for a refinance estimate showing how much cash would reach you after the existing loan payoff, any applicable prepayment charge, fees and other closing adjustments.

Give your realtor the date when those funds are expected to be available. If the purchase deposit is due before the refinance closes, identify cash you can use for the deposit and credit it toward the down payment in your worksheet. Counting the deposit twice makes the funding gap look larger than it is.

Measure what the second rental adds each month

Consider a hypothetical first rental with a $1,100 monthly principal-and-interest payment. An illustrative refinance that delivers the cash needed raises that payment to $1,450. Holding everything else at that property constant, you give up $350 of monthly cash flow there.

Now suppose the new rental would bring in $2,400 a month. Allow $675 for operating expenses, vacancy and future repairs, plus $1,300 for principal and interest on its own loan. That leaves $425. After the $350 increase on your first home, acquiring the second home adds just $75 per month across the two properties before income taxes.

Try one change before deciding. If supported rent on the second home is $100 lower and all other assumptions hold, the combined change becomes a $25 monthly decrease. You can use that result to revisit the offer price, the cash you contribute or the timing of the purchase.

Bring both addresses to the financing conversation

Take the current mortgage statement, a dated payoff estimate and the existing lease for your first rental. For the purchase, bring the proposed price, realistic rent evidence and estimates for taxes, insurance and upkeep. Use the same expense categories on both sides and count escrowed taxes and insurance only once.

Pillar can review cash-out financing on the existing rental and purchase financing for the next one. Each loan has its own eligibility review. The worksheet tells you what the move could add to your budget. Start your application when you have a property to discuss, or check loan options while you're still shaping the offer.
