He is serious.The other son (Sam) wants at least a little money before losing any chances all together and his price is a smoking deal.

Look for mold issues and corrosion.Fire/smoke can be corrosive, so it can have a huge impact on anything that is metal within the structure.  

I walked into the house and the house was filled with heavy oil smoke.

At this level, you want brutal hard, unfriendly analysis, not smoke and mirrors with a big smile.

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 ...

I pre-screened the caller over the phone but after checking her FB I found out she lied about pets and smoking.

Last summer it needed a full rehab--triggered by tenant damage with smoke but went ahead and used it as an opportunity to go ahead and do the upgrades it needed anyway.

After reading the bylaws, they do have a right to enter in an emergency, but this is not an emergency to visually inspect smoke detectors.  

He also looks for other issues real quick like the furnace filter to ensure it was changed, that smoke and CO2 detectors are not disabled, etc.  

Hi Theo,I use the Nest smoke / CO2 detectors.
