Purchase price: $75,000 Cash invested: $600,000 Sale price: $269,000This is my largest new build development to date.

The owner has purchased a property like any other real estate transaction, and they own the physical property. 

@Wade Wisner -  Most of the notes that we purchase we keep in our portfolio and borrow against them with private capital.

Quote from @William Dorrough: I currently either purchase and value add large scale multifamily properties or develop, and build ground up my issue with scaling is we have done this without brining in investors i have a great deal flow with a good track record im really looking to do more i have the capacity but have the need for more capital in one way or another  Scaling without investors can be tough, especially in multifamily.

I have used HELOCs for probably most of the purchases of the properties I own. 

Is this LTV based on ARV or the purchase price? 

Purchase price: $220,000 Cash invested: $45,000 This is a 2 bedroom, 2.5 bathroom rental that I purchased.

Who owns the solar panels and what's my liability if I continue with the purchase?

I'd say if you are looking for commercial real estate wherein the purchase bought the property in a corporation then PS is not the best place for lead generation and skip tracing. 

I hope no one is using this to actually purchase property subject to.
