Smaller safety items  (fire doors, hardwired smoke/co detectors) can often be forced at any time in a lot of cases.

Weather resistant, motion activated (with photocell), bright and efficient LED lights, and super easy to install.

I do mine quarterly, there is a lot that can change in 3 months, batteries in smoke detectors, leaks under sinks, furnace filters, roofs, cellars you name it.

"Go in motion - Stay in motion!"

It wouldn't be unreasonable to base an offer off the numbers the seller provides so long as they look reasonable and as part of your due diligence after getting it under contract go through the motions of actually verifying them through whatever means required.

We filed the quiet title action and on the very last day for the Bank to respond before we received a judgment to void the mortgage, a motion was filed saying the balance was $11,000.

"Go in Motion - Stay in Motion!"

Just recently I had a applicant offer 6 months of prepaid rent, when I went through my standard motions and questions they had lies on there application and with that information was a high likely that there would be no more rent coming in.

I'm sure the snarks on here will say the best tenant proofing is good screening before you rent  :) I personally like tile floors...I have given up on wood...laminate and carpet...provide extra air filters for the AC unit (unless you use replacing them as a reason to go by and check out the place every few months) fire extinguisher in the kitchen...make sure smoke detectors are installed and working properly ...if it is a single family be sure the tenants know where and how to shut the water off ...
