And it's a semi-custom home. $350k is my guess based on my knowledge of the area and what they bought it for at market height.

However, they're the only ones I know who will lend up 100% LTV on a HELOC, and gives me 6.90% interest on cash advances up to $15,000.Guild and Cobalt are pretty popular with investors in the Seattle area, but I don't think they necessarily have the best rates.  

Philadelphia may be a good market to start in :) My only trepidation is, unless your customer is using huge lists/areas, it's probably not worth selling a few hundred names here and there.

He has over 20 years construction experience doing everything from building luxury custom homes to punch lists for agents.

If they're custom sized, then you typically either build out the window opening and buy a std size window or buy a custom window. 

I was wondering which real estate strategy is popular in this area.

Will be happy to get a PM message why is Henry Rappa recommended and if there are others that would be recommended in Boston and very good that their customer service is great and very thorough in their checking / problem solver / deal facilitator 

This live in flip or long term renovation is a popular strategy for people starting out.

Our customers aren't specific to job or industry like oil field jobs since we cover a large area.

All I can say is this: (do research on this)Know your customer (KYC) is the process of a business verifying the identity of its clients.
