Lots of old houses well built and completely upgraded on electrics, windows heating systems etc. and I'd pay more attention to that than the actual age.

No central heating, windows units, kitchens and exterior/yard all renovated. 

Apartment residents noted a need for more storage space (31%); a dishwasher (16%); better Wifi (16%); parking (15%); central heating and air conditioning (11%); and in-unit laundry (11%).Renters are willing to pay more for these amenities.

I do not have a company, just running as a sole proprietorship for the time being.I purchased a property in November 2019 and in 2020 replaced windows, doors, some lights, soffit, kitchen floor, tub, added insulation, heat pumps etc.

Dear Mike in the Scorching Heat (we're in Phoenix; we share your pain):You've got a good attitude about family. 

We are planning to install submeters so that each unit will be responsible for paying their electricity, water, heat, and sewage.

Looking for most economical way to add a/c, also updating heat/water heating.

3)Furnace did not operate when thermostat set, have evaluated, no heat to house upon arrival.Possibly due to thermostat problem but unknown.

In some cases, yes cap-x should be 24%, when you have 17yr heating system, old single pane windows, aged roof, aged carpets, 80's finishes, because all that stuff will be a heck of a pile of $ to replace.

Does section 8 pay a higher rent amount if electric (heating,cooking,water heating,other electric) is included in the unit compared to if its not?
