Example - borrower uses loan to purchase a home in a B or C grade neighborhood for 380k, spends 50k rehabbing primary home, uses 200k to put an ADU in the back, appraisal comes back at 925k. 

I like small units (they don't trip breakers) and they are cheap.

My experience has been that purchase transactions where the buyer has no or little skin on the game have a default rate many times that of buyers who place a significant down payment into the deal.  

Not a one-time purchase.

Why do you think purchase contracts are so long and have such small print?

Your requirements to defer all tax are to purchase at least as much as your net sale. 

the way to go about it is turn it over to your insurance and get the police report.. sometimes insurance will then subjugate the claim and go after the tenant criminally I had that happen on one of my rentals where the tenant did 40k in malicious damage on a new construction home I purchased in MS. 

For me as well as the seller.First, you have to define Sub to financing.Do you mean the reckless kind where you overpay for a property, take over the financing and borrow from others to cover closing costs and holding costs when you have no money, no credit, no income, no reserves and can't tell a warranty deed from a deed of trust and you close on the kitchen counteror do you meanbuying below market value, already having a nice income, having reserves, using escrow and title, already understanding the due on sale clause, have done a lot of creative purchases and know when to use and when not to use creative finance and how to recover if something goes amiss?

@Tayvion Payton here's some useful info:Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

I deal with wholesalers every week on my fundings  or should I say I see their fee's on the HUDS every week.. if I see one come in that is just way to high  like a 50k purchase and 50k assingment fee I wont fund it..
