You don't have to take it out to many homes before it becomes difficult for most to manage. 

Learning how to manage difficult tenants.

I think the difficult part with your advice is that New England multi family market is extremely competitive so going after something worth 1M might be risky because people are just through junk out with a price tag and the CF doesn’t mAtch up all the time.

My first and main concern is that the North Austin market is saturated with real estate agents and getting clients/growing my business will prove to be quite difficult. 

Ultimately, because of my self employment history and spotty income I had a difficult time getting pre approved.

Is it difficult to gauge the closing cost numbers before closing, or are closing costs high enough that they're hurting your returns?

And, a real estate agent to show me the properties (believe or not this has been the most difficult part of this journey).But, I still need your guidance...for the things that cant be learned here...I have my own questions, but I would benefit tremendously from your input as well :)I must make the best out of this trip since I am looking little far from my backyard. 

Your question if a house is difficult to sell if it had previous foundation problems, I've never had an issue selling a house if I can show that it was repaired with a warranty, even if the warranty is not worth the paper it's written on.

It's incredibly difficult to determine the short term market.

Without knowing what the loans would be from him, the interest rate, and the potential profit, it makes it difficult to really judge this agreement.However, based on everything but any potential loans now and in the future from him to you regarding the cars, I will give you the following analysis:1 - Your cost will be $150k (the cash DP).2 - Assuming no cars are involved, based on the projected yearly CF of $18k/year, it will take you over 4 years to reach the $75k in profit you will get before he takes any share of the profit.3 - After you get your initial $75k, you will be getting $37.5k (your half) in CF from then on. 4 - Since the first $75k recovered half of your $150k DP, and you will be getting half of that after that, it will then take you a bout 9 years to recover the other half of the $150k you paid in cash.
