@Dillon Hudson - It sounds like you are planning to start slowly - The best play is to buy something close so you can self manage - I would buy a house in the woodlands - opportunities pop up every day - get something small in Grogan's Mill, Panther Creek, or Cochran's Crossing - with interest rates where they are (for now) you can find decent cash flow with 20% down.  

I'm guessing you're self-employed, the bank will likely want 2 years of those tax returns to show that you're making good money which I'm guessing you have if your stock piling 15k/month (congrats!). 

There are a few self-contained guides that you can access here: https://www.biggerpockets.com/guidesI really like the alerts feature that can quickly guide you to current topics that might interest you: http://www.biggerpockets.com/alerts

@Brock Mogensen  Great points...............I'm actually looking into single raise syndications myself.....either value add multifamily, self storage and/or mobile home parks.

You will find that most of us self manage, some from many states away.

Self help eviction can get you in trouble(shutting off utilities).

Develop your own screening process if you intend to self manage.............don't continue with that PM.

Being a passive investor self-managing all my properties, it is important to get them close to Plano/Frisco and relatively newer.

Keep them in place on this one, and if you want to self-manage in the future, you’ll learn how they do it.

Are there any park amenities that need ongoing service (pool, laundry, etc)Is there any deferred maintenance (roads, landscaping, pads, pedestals, etc)How are they managing the park currently (3rd party management company, self managed?)
