Personally, I think I would stack some cash for a year or so while I did this. 

However, I also have ways for them to pay with cash, card, money order, cashiers check, and personal check.

With the high interest rates it hard to get much to cash flow with the traditional 30% down. 

@Rajesh Kasturi My favorite MTR market for cash flow AND appreciation is Portland, OR. 

This could turn a potential loss into positive cash flow while protecting your property’s value.

Any laws against repaying the loan in stocks instead of actual cash?

I had a heart-to-heart with the contractor and made it clear what our expectations were and no more money (he was asking for a second payment of a three payment contract) would come his way. 

If you want to put down a low down payment, you might not cash flow for a few years.And FHA for 3-4 units is almost impossible.

Now purchasing a home with cash is always good b/c obviously cash is king but also I think the part you might've missed is that, the money your utilizing on these home's won't actually be yours, but the banks or whatever institution you used to fix the home or make its value worth more.

If you do have to move because of a job, you would be safest (in my opinion, i am not giving legal advice or financial advice), i would sell that property to ensure that you did not just purchase with the goal of moving out early and taking advantage of lower rates and lower down payments for purchasing your home as a primary residence.
