I don't know your area and what the market conditions are so it is not responsible for anyone who doesn't know the area to tell you what to do.  

I agree with you that I am almost never on budget, mostly over, but I try to bring the mouse in a condition where all components have at least 10-20 years of life left (which means replacing a lot of course).One thing that you do and I think I will change is to not finish the basements.

The lease itself explicitly states no pets:12.PETS:No dog, cat bird, fish or other pet or animal of any kind may be kept on or about the premises without the Landlord’s written consent.See Pet Addendum.Here is what the Pet Addendum states:THIS AGREEMENT is attached to and made a part of the Florida Residential Lease Agreement dated January 11 , 2015 by and between  xxxxxx(Landlord), and xxxxxxxxxx (Tenant), for the Property located at xxxxxxxxxxxxxxxxxx.Tenant desires to keep a certain pet described below on the Property and the Florida Residential Lease Agreement specifically prohibits allowing pets on the Property.The Florida Residential Lease Agreement is hereby amended by this Pet Addendum to grant such permission to the Tenant.

The geographical conditions of the area must be stable in both economy and future prospects.Take a careful knowledge about the real estate details.

You pay your debts, you are not negligent, you keep the property in good condition, you have good lease agreements, give an equitable consideration to a tenant to hold you harmless and indemnify you, so that agreement holds water.

Price, physical conditions etc..?

My exact wording on the signs:SELL YOUR HOUSEFAST FOR CASH(xxx) xxx-xxxxANY CONDITION/SITUATION

What kind of condition is the property in?

This means it's in her best interest to leave it in perfect condition so you can turn it around quick.  

In my area I can get a 3/3 duplex for $140k in an A/B area that can bring in 8-900 per unit.  3+BR sfh go for around 100k in rentable condition.  50-60k in need of repairs.
