I understand how important it is to expand your presence in the online marketplace to reach a wider audience.Given the complexity and technical aspects of e-commerce, I would advise you to seriously consider enlisting the help of a professional e-commerce development company.

Whenever we get an application from someone that we get on Furnished Finder (and full disclaimer... we are new at this so haven't done a lot of them yet) I ask for their recruiter and staffing agency on the application and add it to a spreadsheet.

Technically everyone was a stranger before they moved in and we've never had any issues of stealing or squatting or any type of damage to the property.

Technically neither do you since you aren't legally allowed to enter the property until you are given a deed.

. % of allocation is a separate technicality, and my colleagues already commented on it. 

To summarize, alot of the issues you are experiencing can be mitigaged with proper contract management from the start as it offers the ability to understand staffing and the many relationships and contract participants.

With conventional financing, changing the deed over to your LLC after closing is technically a violation of the loan documents.

Things like valet trash, cable contract reimbursements, RUBs, common area expense budgeting, proper staffing levels, AI revenue management, PPMs, subscription agreements, blue sky filings, commercial lending standards, commercial building codes and permitting, ADA compliance, etc.  

PHAs administer "owned housing" these are usually multi-family complexes  but may have technically SFDs as 1-4 units but usually in a complex of similar units.

I've heard that it's better to have a commercial property insurance policy for the LLC that covers all of the rental homes in it since A) it may be more cost effective than having individual normal home insurance policies on all of the homes and B) it will name the LLC as the primary insured party which technically will be the primary insured since the homes will be in the LLC's name.
