I've found luck obtaining information/licensing requirements first on the county's website under zoning, and then reaching out to the specific town/city and verifying any further requirements they may have over the county's.

I'm a trust but verify guy so 3 times a year we have picture inspection reports done so I know the condition of the unit, cost $75, Will share information if requested.Best,Mike

Verifying last 2 years of rental history very important!

You need decent credit and some skin in the game. (15%-20% down + pay for closing costs)Typically when investors call me i will go over the numbers with them right on the phone and verify the deal fits our box / give pricing, then I'll take the time to do some comparable sale research to verify if your estimated ARV is within reason. 

Conzy you can Trust Dmitriy as a fully vetted verified source for what is legal.. when you make post like this your going to open yourself up to fakes frauds and scammers contacting you so if that happens be very careful send NO Money.. etc.

You should verify whether you can establish this type of LLC in Texas. 

Hi @Adam Davis,While you may not qualify for a conventional loan, there are non-qm loan options that can go off of your bank statements and credit score without having to verify your tax returns.Your thought of getting the loan and only paying when the house sells is not an option.

In addition to what Michael said-if you do go ahead with purchasing it, write in the offer that they can not rent out the vacant half, deposit from the occupied side is transferred to you at closing along with prorated rent and get a copy of the lease that has been verified.

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

@Mark Cruse and @Nathan Gesner are right on track, as usual....People are all too happy to rain on your parade, especially when they have failed themselves....misery loves company...It's kinda like verifying that they couldn't make it and therefore no one can.
