Our goal is to acquire a mixture of properties single-family and multifamily to buy  and hold

Will getting a RE license REALLY help you acquire that FIRST property?

In addition, start looking at deals immediately and get familiar with the numbers in certain areas and rehab costs.

I've recently come across an opportunity to acquire a property via seller financing.

You mentioned not wanting to invest a lot of money, and that's fine, but having additional capital may still be required.  

What is it you're looking to acquire?

The hardest part that I'm facing is getting into the market in Lubbock as most developments have selected builders and most lots have been acquired by other builders.

Being that you are in Japan that ads additional difficulties.  

Free cash of $1,300/month (the $1,150 you are currently paying in mortgage and utilities plus $150 cash) could then be used to pay towards principal on SL and car not, accelerating debt pay down.78% RR on 20k minus 5% avg SL and Car interest and 4% mortgage interest = IRR of 69%I think (assuming I'm looking at this the right way), using your 20K in cash soldiers to generate additional income is more advantageous than using it to pay down debt.

In addition, I'd own the liability of paying for stuff when it breaks, and my insurance would cost more.
