Take ownership of your mistake and learn to do the proper due diligence recommended above😊

I would absolutely collect that from them if they were properly notified

If they do allow it, a third unit will need proper egress to get confirmed.

Agreed with the above posts,  for $500 or less you can likely get a RE attorney  to get your ducks in a row to do the eviction properly.  

Probably best to look elsewhere accordingly, as the availability of properly zoned STRs is quite limited.   

Again contact housing authority and request a FSS coordinator who should have more info. 

Established flippers have the resources and networks to build close relationships with contractors, making it relatively easy to coordinate compliance at minimal cost.

I see the value in not being overwhelmed because of a failure to properly build a situation with systems and organization.

:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+ (roughly 5% probability of default), zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680 (around 10% probability of default), some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

So outsourcing some degree of property mgmt would be a must... but the deal won't work paying a local property manager a large % of my revenue...Instead, I would set up my "boots on the ground" (cleaners, handyman), and would need an offshore virtual assistant to manage guests and coordination of my local team.
