I am obviously in real estate, but my fiance is a programmer and hed still need to work.

As I'm thinking about it, there were no thermostats in the units either.

For gas, install a thermostat outside the home so tenants can't control the heat in the winter. 

But if your child as a roommate, all bets are off - you are now subject to the fee, inspections, and energy efficiency upgrades (the expensive part - attic insulation, low flow everything, new toilets, AC inspections, programmable thermostats). 

Self managing has become much easier than it was years ago, with the advent of smart locks, smart thermostats, and other things that help manage from a long distance.

Nothing wrong with Quicken, but I was in IT, System Analyst and programmer with companies large and small, and more familiar with double entry bookkeeping.

The thermostats are located in the basement and set at 70 degrees, so tenants can not raise.Cost of doing business there.

The YTM can be approximated using a bond value table (also referred as a “bond yield table”), or it can be determined using a programmable calculator equipped for bond mathematics calculations.

The floors were extremely unleveled and the new flooring was already coming apart, in one unit a previous landlord spray textured over every surface of the property including the thermostat/door knobs/trim, in both units the kitchen and bathrooms were falling apart and barely above usable condition, the staircase in one unit was obviously illegal it was so steep, and the walls/ceilings in both units were a mixture of poorly cobbled together panels, cracked lathe & plaster, suspended ceilings that should have been replaced a decade ago, and entire surfaces made from something I couldn't determine.  

(**THIS IS ONLY FOR VERY EXPERIENCED BUYERS)  When you do your 2nd showing on a property you really like, schedule to have a contractor or retired inspector or builder come with you to identify any of the super major items that would cost a fortune to fix and do a mini inspection (IOW, test water pressures, run dishwashers, get outlet tester, turn thermostat up or down to check appliances are working if possible, etc.
