Not great in general.At the end of this, I will write a more formal article outlining these profiles.

the problem is my fellowship is in the form of stipend. they dont have formal paystub. the only thing i have is the bank have a record of my income each month.

I'm not sure if the tenants have formally put in a maintenance request that would require it to be fixed.

I am a formal mechanical engineer, turned real estate investor (i know!).

Alex,I find most RE investors that have entities hold property in LLCs as this provides the most flexibility at the lowest cost.Corporations and LLCs have almost the same "formality" requirements, so don't think that because you have an LLC you don't have to follow the formalities.

I have been presented with  an off market deal in the Clinton Hill/ Bed Stuy border in Brooklyn

Resort style parks do not have tenants but 'guests' who are on month to month (or shorter) agreements and can be removed without a formal evictions.  

I have investments in the Chicago area, Indiana side of the border though.

A lender should be able to give you a more definitive answer or have an underwriter look at your file.I would recommend having the lender review all your documentation and giving you a formal pre approval.

I just don't see the same potential for East Boston and I would stay far away from the Chelsea border, that is in my opinion the last area to appreciate there.
