I like my landlord just fine and there are zero issues on either side concerning payments, repairs, upkeep/cleaning, or anything else.

Increased rents on first floor and moved into top floor.

Brother living in top floor, other friend renting out 1st floor.

We now have a Flight Attendant managing the house for us and keeping it clean and organized.

I see perhaps a new kitchen, paint and maybe a little flooring. 

I think in the last few years the syndications cleaned up.

We added value by repainting interior, new floors, new roof, resurfaced the pool, added a fence for privacy, upgraded the landscaping, sealed and painted the exterior, added central A/C with new unit, upgraded the irrigation system, added gutters, added security cameras, added hurricane proof front and rear doors.

Your house looks very clean and new, but lacking a little character with no artwork. 

I hired a virtual designer for a few thousand dollars and after giving her dimensions/walkthrough she had a buy list and floor plan ready in two weeks.

If so, it will be nice and clean since you will be their agent.
