We had the most expensive rental in the entire city at the time of listing and we got great tenants that met all of our requirements.

Mine were eaten by squirrels two years ago and weird weather last year killed all of the peaches in my state.I'm planning on putting sheet metal around my tree this year and spraying Pam or something else on it so the squirrels can't climb it.

Example: those you mentioned in CA, IF they are metal roofs, then sure they'll last 30+ years. 

--There is also an old school house with metal roof turned duplex that brings 1200 monthly.  

Additionally, each floor is equipped with a central vacuum for easy cleaning.The house is adorned with beautiful white oak hardwood flooring, and the metal floating stairs are custom-made, adding to the modern, luxurious aesthetic of the home.

New Metal Roof, New Furnance, New Floors going in soon, as well as a new bathroom, and a basement wall fix What was the outcome?

I will read the book on estimating rehab cost too.Another interest of mine is car racing and I built a racecar "Scrap metal" completely from scratch.

These metal sign posts are pretty cheap, and they stick in the ground easy, without any pounding.

Anyway, here's the quote my property manager got:3.0T Down Flow 80% gas Furnace 3.0T coil 410a coil 3.0 T 14.3 Seer CondenserNew thermostatSafety switchCondensation pump1 supply plenum2 Solid return boxes$7,315.00This comes with a 10 year warranty on equipment and 1 year labor.This seems way above what it needs to be. 

I don't really want people running fridges/freezers or electric heaters (these are metal non insulated units).
