You want to make sure that a lawyer closes this deal, that way you are covered if the note is bad or if it doesn't get recorded, you can sue.  

It's a 6 unit building that is in need of a total rehab (already gutted to the stud) I have a partner that will cover the entire rennovation about 180k.

No one is ever 100% covered, but you want to cover what you feel most vulerable. 

There's a lot that needs to be covered in a real estate contract. 

Other than that, looks like you covered all the expenses.

There was a recent podcast that covered this GREAT.

However, I want to know if there are deals where buyers can use the help of an investor to cover the cost of a downpayment, in exchange for part equity ownership? 

Plus the PMs I work with know that keeping an existing tenant is easier than loosing one so if they charged me $150 to resign an existing tenant for another then I would expect the tenant to cover that cost over the year.

I would cover myself by making the offer contingent on property inspection.

Amfam says they will give me a HO5 and State Farm says their broad form is better than HO5 and will cover everything?
