He not only wont pay you back, but does not communicate anything with you.

Based on your numbers, this seems to be a Section 8 duplex, is that correct?

In general, i think Stuart is correct.  

And one more question I've worked with 3 REA thus far but so far none of them communicate timely (it usually take 2-3 days to get a response even when I'm letting them know I want to offer on a property) is this common?

They had excuse after excuse and one of them even stopped communicating completely. 

However as you correctly point out this is far more risky and or its risk capital compared to buying a income property.. but the reward can be strati-spherically higher .. not just a little bit but it can be life changing profits on some of these deals.

These are typically 'non english-speaking' neighborhood so to speak for political correctness. so parking while already become a problem, but adding ADU in that neighborhood would not become a problem because 'everyone knows each other' everyone has their own unit.But that ADU thing, is bit uncommon in 'english-speaking neighborhood' LOL, so that's where "some" people is complaining about parking space and so on and so on when one home is building ADU.For me, I prefer to have ADU on the hill side, now we have 15 car space and from one neighbor to next neighbor is like quite distant.

Balance (compromise) and communication are key in situations like this.

Red River Gorge...New Mexico, correct?

If investors attempt to streamline their services, it can lead to a more organized approach to property management, lowers the risk of gaps in insurance coverage or missed tax benefits as well as simplifies communication and reduces confusion.
