I'm considering AirBnB - looks like FF is a no go.

They borrow just enough money for the house or they finance just the house, and depend on the rents they receive to pay for any extras, which is a no no. 

If you are looking for a return on investment then it's a no-brainer to look out of California, of course.

The property is damaged significantly by tenants and previous owner negligence .Maintenance has been neglected over years In one unit tenants claimed 10 people in Estoppel certificate and in section 2 of Estoppel they claim: a)no occupancy limit / no household limit b)can sublease c)can have roommates so basically they are renting units themselvesIf you have any experience on this please help or contact me 

I have a no claim history. 

When a tenant is late on rent, causes too much noise, damages the property, or violates the lease in some way, you'll have two options: 1. enforce the lease (which is being an effective landlord, but you'll probably lose the friendship), or 2. let it slide (which means you might keep the friendship, but you're not being an effective landlord)...it's a no-win situation. 

Even with a no doc DSCR loan you are required to provide a credit check and proof of funds

@Ricio MontesAdding ADU's in the current RE environment is a no brainer.

They run your credit and that shows so if looking to invest with SIDRA and be totally remote it's a no.

Well my heart is telling me it’s a no brainer for the PDF reports you can run on it’s own.
