I don’t place all the blame on him, as I understand Massachusetts law is heavily tilted in favor of tenants.

I've done plenty of work in the past for him where this is simply returning the favor to help on my first property!

Hi @Leonard La Rocca III welcome to BPWith a goal to house hack your option will be much better and tremendously more favorable.1. $50k gets you the house but leaves you very little room for value add. 

And, probably the biggest, the fee and waterfall structure are much more favorable to the GP when your investor base does not have many options.As for advice, the best is to view many deals and talk to many operators.  

That's a relationship you should hold close as they could really help with future challenging acquisitions that are viewed less favorably by banks.

And you assume the rest of the mortgage that you're already guaranteeing.Your idea to refinance immediately after to get favorable financing is perfectly fine. 

No one will ever thank their landlord for doing them a favor- at some point, they'll have to pay market rents and you'll be the evil slumlord when that day comes, no matter how nice you've been up until that point. 

Judges have been mostly supporting the "lenders" side in court actions, but, occasionally, one will find in favor of the borrower. 

Do all lenders give favorable terms when trying to do this.
