They've secured most of the capital needed for a flip (deal is 110k purchase + 120k rehab --> 440k ARV appraisal) and are looking for a 2nd loan for cushion. 

I am located in a unique area of the DMV (D.C,Maryland,Virginia), so I am accessible to these areas as well as West Virginia.

Unique opportunity for individuals to become a part of large Multi-Family Development.

Another Boston area that is very desirable would be Hyde Park and Roslindale where you're in the city but those areas have their own ecosystems and cultures that makes it very unique.

I realize it is a complicated topic and each individual circumstance is unique and probably requires professional advice. 

Make sure you credit score is solid. you are opening two new lines of credit at the same time, so you need some cushion.3.

I think you can get a loan for less than 6.5% but i would leave that in your model just to have a little cushion.

Question:Does anyone have some advice on how to handle this unique situation respectfully and professionally?

I also had a good savings cushion (15-20K) and zero debt so that helped immenselyANYWAYS - if you're really content on flipping and figuring out how to do it, you should check out J Scott's new book on how to flip houses.

I've taken some numbers from the sellers proforma, but accounted for some cushion on the expenses in case they are higher than what is listed.
