Yup, they both have their demons to tackle however, our investing was in WA state because there were no AC condensers/freon and complex boiler/chiller systems like there are in TX/FL plus property taxes are around .8% of FMV or fair market value annalized while other states are higher especialy TX, FL.

Also condensing these purchases can give one a monopoly on rent control as well.

When you're paying off so quickly, it's less about interest rate and more about interest cost, and how much interest is paid over that condensed timeline. 

Also here is the scope of work since I didn't post it before (I don't think I did).SCOPE OF WORK:Roof - Approximately 5 year oldExterior- Home will be paintedWindow Repair- Repair or replace any broken windows and repair all rotten woodPressure Wash- Clean dirt and other debris off of the exterior of the homeLandscape - Trim grass and shrubbery and add fresh mulchNew MailboxNew HVAC- Brand new system with caged condenser (includes new furnace)Plumbing repair- Repair plumbing system to ensure proper function and install new water heaterIron Security Doors x 2- Iron doors to be installedRekey- All doors to the propertyElectrical Repair- Perform an inspection to ensure all outlets are in working orderInterior Paint- New paint on walls and trim where needed.

Air conditioners must be positioned to allow condensation to drip outside the building, not inside.

Is it a new Complete system new furnace new coil new condenser ?

Is there a shorter, more condensed version of this document that I would be able to use? 

To name a few issues indicated; units have a known history of water management issues related to workmanship detailing, soft/weak spots in the wood laminate flooring, damaged vent caps on the roof, water leakage in all 3 of the units, condensation observed dripping from main water service, with staining.

I was able to save money on the roof, HWT, and AC condenser because they were all less than 5 years old.

I've seen AC condensate pump lines that were operating properly, discharging onto the roof, get bent over and decked over, that continued to pump water into the ceiling void destroying three floors of apartments over a two year period before the cause was, literally, uncovered.Water runs downhill, and looks for the easiest path to do so.
