@John Moon yeah, 2 main types of loans for what you described:Fannie Mae/Freddie Mac loans - these are "conforming, conventional" loans. 

Depending on how you plan to allocate your overhead (for instance- if hours are you main cost driver), you may want to integrate with some other apps on the platform.You may want to speak to an accountant that has worked with implementing these types of systems (apps + job/project costing + class tracking) as they could help point you in the right direction. 

My main goal is to house hack my first triplex or quad in CNY.

Typically an ADU is inferior in size to the main improvements.

-Units are same sq ftg (approx 500 sq ft), but one is a studio and one is an actual 1 br-Fully renovated (floor-to-ceiling) units of the same layout and size in the complex are selling today for $155k-$180k (big range, but supply and demand, right?)

I'm also hoping to try out the BRRRR strategy in some of my future deals.My main goal is to connect with as many members on BP as I can and help others in their endeavours while learning about real estate investment myself.

@Jon Ankenbauer speaking from a lenders point of view, the seller carried seconds went out some time ago with most of the main buyers of mortgage loans.

My main questions are around how to structure entities, taxes, profit handling, and overall process.Thanks!

It is true few people understand the money supply.

Will there be excess supply of houses in the years to come after the baby boomers are no longer living in single family housing?
