ALSO, I have not had to do an eviction following a partial payment agreement (so I don't know exactly how that would pan out in our courts), all of my tenants have so far completed their payment agreements as signed.Multifamily Northwest has forms for these types of things available via the Rental Forms Center at https://rentalformscenter.com/ Their forms are typically well reviewed by local attorneys; as you'll note, on the Partial Rent Payment Receipt there is verbiage specifically about if the landlord has/has not served a termination notice and reserving the landlords right to eviction if the agreement is not completed. 

@Giacomo Matthew Degl'Innocenti   Sounds like you should buy instead of rent 

Sounds like their combined income likely beats your other tenants.Your gut is probably your best bet and you need to go with it. 

Anyone wants to know how to complete the form, here you go:Corporate Transparency Report - How to complete the BOIR (biggerpockets.com)

Once completed, the goal is to get them rented and then pull money out of each house to build a high performance spec.

Prioritize tackling critical issues and beefing up security to keep your property safe and sound.

I'd also suggest considering a partnership if you feel comfortable with that in order to reduce the risk completely on you. 

Others needed a complete overhaul.

That sounds cheesy until you talk to people who have lost their purpose.

A complete overhaul of the kitchen and bathrooms, including cabinets, countertops, LVP flooring, electrical and plumbing fixtures.
