If you choose to accept it, make them apply and pass your screening, add them to the lease, and charge extra rent to make it worth your trouble.

I am curious if there are any pre made criteria lists out there or if there are any “must haves” for tenant screening. 

Tenant screening is, in my opinion, the most important step in maintaining both your property and your sanity. 

., and pick it up in three days, and in colors and sizes not picked by a homeowner, there is little or no bidding.

@Stephen J Davis It looks like the issues you raised are with your tenants and tenant screening. 

Enlarging master bath: again, this depends on the size of the bedroom itself and still being functional in its smaller format.  

My experience on the forums is that everyone who touts a one-sized-fits-all system is (when you look at their profile) a paid teacher, coach, guru, etc.

Depending on the size duplex you get market rental rates are $1000-$1250 in Lehigh Acres. 

Calculate the size of front and back, then do the math.

Here's what I would do if I were in your situation today: 1- If you compete with multifamily properties, due to proximity, price, and/or size, I would call those close to your property (pretending to be potential tenant) and and see what they are doing to get their units rented.
