PS- any recommended sites, apps, books on broad and specific market analysis you might have would be greatly appreciated ! 

The investor cash flow loan doesn't require any employment or income on the loan app.

It's up to you whether you want to pay their app fee, but they are completely legit. 

Although some markets have more popular listing sites. 

Apps, social media tactics, etc..

I'd guess the property has a legal use / number of units.Representing a flophouse as a 4 plex sounds like mortgage fraud.Although if legal use is flophouse your app for a 4plex loan will not fly.So, no fraud.

Really cool, and this was right before it became quite popular, and before everyone had heard of Airbnb.

What apps do you use to list your rentals in Houston besides har.com and Zillow?

When I used Cozy and Zillow, I still had them fill out my app so I had this info just in case, and I checked the local courts for evictions myself.What I did like about Zillow is that they could use the application for other apartments if they were turned down for my apartment. 

Just to give some background.I started with apps like Opcity.
