I don't believe that Countryside was sandy soil though.Steve

I am looking to raise the rent on some tenants that are underneath market by about $200 but also are in units that are fairly outdated.

They often recommend a phase two environmental report, which takes soil samples. 

We did lots of cosmetic fixups - painted, ripped up the groddy carpet and refinished the hardwood floors underneath.

I'm assuming you would need an engineer to sign off on the foundation to build however, would there be any issues with cleanup, soil testing, anything like that? 

Tenants without a washer/dryer will see this as another big moving expense and it may prevent some of them from renting.The benefit of NOT providing them is that they get moved out so you can clean underneath and the hoses are changed regularly.

Ended up moving in as primary residence for five years, market tanked and we sold paying $3000 toward closing costs to get out from underneath it.

Taxs need to be fully understood and soil conditions. and make sure you have great wind insurance as wind and hail damage is real there.

Foundation issues happen a lot due to the soil in Texas I personally chose too invest elsewhere when I was living there but it’s a great market economically

Make your offer in a way where those expenses are underneath your loan.
