We have a Chicago general contracting business, and handling the field operations is a ridiculously heavy lift.As far as finding customers I think you'll have some good success with gorillia marking at some of the local investor meetups. 

I don’t need help often but have had good luck with customer service when needed.  

If they need to reinvest, how does sub to help them accomplish that goal?

If you have more than 4 or 5 loans, then you might want to engage a sub-servicer to handle the billing and payments.

A lot of people (myself included) use multiple baselane accounts and sub-accounts to keep things as clear as possible relative to each property.

I'm a Project Manager at an Architectural Firm specializing in Custom High-End Homes. 

Let me just lead with EXCELLENT customer service.

Also know that building a home seldom goes as expected - I have relatives that just built a nicer house… they thought it would take 9 months… it literally took 18-24 months between delays in permitting and the builder just not being able to get it done in a timely manner - often due to sub-contractor issues.  

They pay the sub by check , the sub deposits the check , pulls out cash and pays his guys in cash .

Ideally 70-75% LTV and sub 7% rate.
