I wanted to submit an offer and get my first deal but I didn’t because my contractor said he probably would pass on this one because the foundation was like something he’d never seen before. 2 rooms had concrete underneath and some didn’t.

Removed that old carpet we all love... just when you think you’re going to get lucky and find a nice sheet of plywood underneath, you get stuck with this:Do any of you experienced DIYers, or contractors have any experience with this?

After inspection, sellers confirmed it's somewhere underneath the carpet and they have denied us access to pull the carpet bc they don't know the exact location of it (units are occupied).

Maybe also look into the soil type of the lot?

They are also attracted to moisture, such as from a leaky pipe underneath a bathroom sink or a wet bathmat on the floor." 

What is the Market value and what is the offer price, herein lies the solution.Damage is done to carpet and underneath.

Hey Tim,Researching OOS markets is new to me, but in also seeking landlord-friendly states with good foundation soils and reasonable property taxes (not TX), no or low state income tax that also don't face storms, snow, earthquakes or flood for the most part. 

Minimal repairs needed, just some ugly carpet with hardwood floors conveniently underneath.

The day I was going to remove all contingencies, my contractor while sending plans to the city found out that ground soil the exist house was build on was basically back filled decades ago so it was not conforming to todays standards.  

If it leaked you will have a clean up that could remove lots of soil.
