If you tell a wholesaler the zip code, the SF, the bed/bath and condition they should have a ballpark in their head instantly.

You can even sweeten the pot by telling them they don't have to clean, and you will hand them their deposit on the day of move-out after a 10-minute inspection to verify there are no damages.

If you are self employed you can also look at bank statement loans assuming you have a business with high deposits.

I love when an agent says "investor opportunities, instant cash flow", then they don't even have the current rent amounts listed or the lease terms.

Have them direct deposit into a separate rental account if you can.
