He at least needs confirmation that the repairs were done correctly.

It's a very clean and well kept property and the only improvements I would make for a rental are maybe heat pump replacement & bathroom remodels.I'm not sure if that would be enough.

There is money to be made in all market phases, but those that aren’t prepared to operate as the market heats up aren’t going to enjoy a long run.3.

If you really want to get nerdy, you can check out the solar heat gain coefficient ("SHGC") for the glass along with the U-Factor.

@Dimitri Wilson most of these look like valid complaints on the surface: lost water, no heat, frozen water pipes, water damage in the bedroom, toilet leaking, etc.I just took over management of 24 units that the owner was "managing" on his own.

This includes: Fire rated ceilings or walls, smoke detectors, co detectors, fire rated doors, separate electrical and heating systems, and probably some reconfiguration of the interior. 

Is Poble Sec providing you projects lately with the market heating up?

Each unit has its own meter/box and tenants pay for central heat and air for each unit.  

Just heat tape them like you do mobile homes .

The maintenance fee is not very high, nor very low, $360 includes heat, hot water and gas.
