It's a traditionally very low income neighborhood.

I spent a great portion of my life in school and as such lost out on a lot of financial/investment opportunities since I was in school or in low paying jobs in order to gain experience.  

I wouldn't use a number that low for a 3/2 house much less a 10 unit building.How about 3k-6k per door as an estimate then adjust from there after more due diligence.

He charges reasonable rates to manage my 15 units, and is extremely responsive and diligent. 

The group is extremely motivational, and quite useful for networking.

I would think you would only do calculations based on what you plan to do to the house, but I am curious what others thinkI haven't had to worry about this yet, because my properties thus far are relatively low end homes.

Im not commenting on the unwillingness to provide details or personal info but in regards to the 12 months in advance that is EXTREMELY common in the Asian community so don't let that part scare you away.

Great insight as I'm licensed and deal with low priced homes with high cash flow.

I have 2 properties so far with him and I'm extremely happy with my experience. 

Eg they borrow at 4% and receive say 7% giving them a profit of 3% for no money down but a little time for the loan app plus the risk associated with repaying the loan if it goes belly up - though with 20% of my cash down the risk is low for them.
