I would pull permits and do plumbing, electrical, and finish work myself while living in the garage.

Perhaps more, a lot more.Next, you need to add in at least one new kitchen, including all of the plumbing and additional wiring.

We are doing bathroom remodels, flooring work, deck repair/replacement and some minor plumbing issues. 

Things like basic plumbing, finish electrical, fence construction, paint.

If you replaced or repaired any plumbing like sinks, bathtubs/showers, water heater, etc., there would have to be test of the system.Is it possible that the water is only turned off at the incoming line inside the house?

Replaced galvanized plumbing to kitchen.

You may have plaster and lathe instead of drywall, plumbing that consists of a hodgepodge of various outdated materials, who-knows-what kind of electrical components instead of a modern system designed to handle modern loads...

I would be interested to know from someone with major rehab experience if these numbers would work, specifically the rehab amount for hvac, plumbing, electric, as well as all interior finishes.

You can also have your PM do a quarterly check and have all of the tenants aware of this; check the mechanicals, under the sinks and any other plumbing.

I reported to active duty in the United States Marine Corps in October of 2011 and committed to paying off both loans with the rents and my paycheck—I did so within two years.When I bought the property, it was gutted of all metal, electrical wires, plumbing, appliances and fixtures.
