You can't stop a tenant from bringing in their own roommates if their space legally can accommodate the extra people (and there is NO enforceable occupancy limit if you rent a single family house),  and you can't meaningfully screen those roommates.   

If someone requests a lot of accommodations or wants to change the lease at the last minute, those should be red flags as well.

Almost all of our units are two (2) bedroom, so we design the island or peninsula to accommodate 3-4 people seated.That way tenants have a place to sit and eat, and they don't have to take up a bunch of floor space for a dining room set.

I would recommend researching real estate investor specific attorneys and those that operate in multiple states so that as you grow and purchase properties in other states, your attorney team will be able to accommodate your needs.

We have two kids, and my husband is unable to find work that will accommodate his current disabilities. 

New hotels, accommodation unites and apartment complexes are in high demand, driving the real estate market investments.

They responded with a request for disability accommodation that we must rent to them due to their disability. 

But, the above letter should knock out most applicants.And I think landlords forget that the tenant must ask for a "reasonable" accommodation based on their disability.  

I have a check-in time after 2PM, check-out by 10AM and get regular requests to extend these times, which on occasion I try to accommodate but limit this keeping my cleaners on a regular schedule, giving them some flexibility to clean the place thoroughly. 

(That is of course considering that the improvements are easy ones to do while she is living there like patching holes/replacing doorknobs.)If you did want to accommodate an early move in, perhaps the current tenant would be willing to accept all responsibility for any damage until the end of October...
