@Uzair Syed, Ashish is a rock star CPA.

My friend here made her house payment b( and it was a huge house)by renting rooms ( and feeding) Foreign students at our local CC. 

You have a great tenant paying like clockwork, why rock the boat?

Here is what he stated-“A rooming or boarding house is a commercial operation being run in a residential area”.Is going through Air B and B a viable option? 

Title search, back taxes etc all come in here as well.If you've covered any major defects, established rehab or updates needed in terms of cost, run accurate comps, verified tenants/PM's if this applies/they want to stay, verified zoning if it applies, tax rates/title work, local landlord legislation for buy and holds, and the terms of the contract, you should be ready to rock and roll = ) Hope this helps!

A soil engineer will use a much deeper hole, often 7 to 10 feet or deeper, as they look for a high-water table and the presence of rock ledges or impermeable soil that could block water absorption.

@Yuzi Stha the vast majority of duplexes were built in Austin and Round Rock between the 1960's and 1990's, so you'll be in core neighborhoods with likely no HOA.

If she tells you to kick rocks then when you go to court you have ground to stand on and show you are doing your diligence. 

From people like Black Rock coming in to buy residential housing because almost every alternative is horrible right now....

HVAC is noted to be 2 years old, new stairs for second story, new sheet rock.
