Quote from @Brandon Le: Your first purchase could/should be a house hack.

Always introduce yourself as ..John or maybe Reagan is better....Maybe like hi I'm Reagan like the President, your friendly neighborhood realtor....that's how they will remember you and you want them to remember you. 

You want to look at paragraph 12 of the Texas purchase contract, called the 'One to Four Family Residential Contract'.

For an $800k investment purchase, I would expect $200k downpayment, $10k-$15k in closing costs, and 1-3 points at $6k/point.

Buying a property as primary, renting a bedroom or two to friends is a good way to start building your RE portfolio.

The second is a rehab property that I purchased for myself, I purchased it out right for 100k.

@Mike ReynoldsSeller financing is allowable for Solo 401k purchases.

I'd say if you are looking for commercial real estate wherein the purchase bought the property in a corporation then PS is not the best place for lead generation and skip tracing. 

Let's assume the financials in the package are good for a moment (they probably are not) AND that you either do not or do achieve the broker's pro forma:If you purchase this asset, achieve ONLY the 'current' NOI, grow NOI 2% per year, and exit at a 5% cap at the end of Year 6, you will have a 4.8% unlevered IRR. 

Keep in mind, it would be in your best interest to go for as high as 4 units on each purchase to maximize your door count.
