You can be doing real damage to other people with unethical behavior like this.

They always bring a furnace filter, etc to ensure that gets changed and it helps make sure there isn't any big ticket items being ignored or damage being done.  

I do have a bad habit of saying less with more instead of more with less - sorry.Yes, the reason I won't allow pets is because of the tenant and how I don't trust them to a) take care of the pet and b) pay me for damages and c) not create damage that can not be undone feasibly by either party, landlord or tenant (cat pee)I also don't want the hassle of enforcement.

A seller, whether a builder or individual, can sue you for one of two things....either specific performance to fulfill your contract terms, or for damages for the delta between your contract price and the eventual sales price plus other associated damages. 

Of course I know it’s there, the inspector wasn’t worried and advised me to clean it with bleach as it was dry, so it must have been from some older, but since fixed water damage from the 2nd floor unit.

At the very least, you need builder's risk, fire, and liability coverage.What's your plan if someone slips and falls on the site, or if someone breaks in and damages/takes materials or tools, etc? 

They've actually been great about paying me out for damages, extra cleanings, etc. as well. 

Any advice appreciated,Sara B Yea you can do a lot of damage in the Midwest with $35k, especially if you use it as down payment funds.

Read the fine print in the foundation repair contract: Damages to the property, interior and exterior as a result of the foundation movement are not covered, during and after works completion.

I inspect my own properties once a year, I try to take care of the things that reduce later damage like cleaning the gutters and servicing the furnaces.
