The closing day counts for

How it works

  1. 1. Split the month

    Rent ÷ days in the closing month × the buyer's days.

  2. 2. The closing day

    Contracts that prorate rents "through the Closing Date" – like the Texas resale contract, paragraph 13 – give it to the seller.

  3. 3. Deposits

    The buyer becomes responsible for tenants' deposits – so they are credited or transferred to the buyer.

State rules on deposits at a sale

  • Florida: deposits and advance rent transfer to the new owner with earned interest and a per-tenant accounting (§83.49(7)).
  • Texas: the new owner is liable for deposits from the date it acquires title and must give each tenant a signed statement (Prop. Code §92.105).
  • Get every lease and a deposit list per tenant from the seller before closing.

Questions about rent proration

How is rent prorated at closing?

The month's rent is divided by the days in the month; the buyer is credited for the days after the seller's ownership ends. Whether the closing day is the seller's or the buyer's depends on the contract.

Who gets the tenants' security deposits when a rental is sold?

The buyer, who becomes responsible for returning them – in Florida they must be transferred with earned interest and an accounting (§83.49(7)); in Texas the new owner is liable from the date it takes title (§92.105).

What about rent the tenant hasn't paid yet?

This calculator only prorates rent the seller already collected; how uncollected rent is handled depends on the contract.
