They try to use it as last month's rent or fail to clean because they assume the Landlord is going to keep the deposit anyway (far too many Landlords do).

we have until spring of 2025 until our balloon loan either has to be refinanced or paid off (we got this loan because we intended to build, of course) and now i feel like it's a ticking time bomb.we conducted "clean and satisfactory" (no issues whatsoever to build) soil and foundation tests and provided those to every buyer. it seemed (not quite sure here) like they backed out once they reviewed the tests - yet there is nothing negative in them. we will not be providing these tests moving forward (as we had to do them ourselves and feel that each buyer should do their due diligence moving forward!)

Photograph everything before you start cleaning-though without similar photos of the move in condition, you may have problems with some things.Then decide if you want to keep the home as a rental or sell it. 

Knowing my cleaning person, there is no way she left the place like this.

Make sure you communicate to the cleaners that you're hosting longer stays that are over 30/60/90+ days (depending on your market) so they can give you the price for a deep clean.

If it's because there's hail damage or the HVAC is old or whatever, then laughable@Andrew Syrios What about needing to add a clean out and old corroded copper pipes?

but yes it does come down to that.. in tax cert states keep in mind many insurance companies or large corps or hedge funds will bid down the returns to 3 to 5% there by cleaning the clock of every private investor who thought they were going to win at auction.. so what happens in reality is people burn out doing DD and never getting anything . 

They're only selling well below the ARV if there is a giant mess to clean up.

If you are renting by the room, I'd also get a cleaner in to clean the common areas.

I usually do this to help cover the carpet cleaning costs once the tenant moves out.
