Added new plumbing, new electric, new windows.

Basically, i think all i need to close the door the Bedroom to the kitchen area, add an exterior door, add kitchenette, and possibly add its own electric panel.

Make sure that you have an inspection period of a couple of weeks to get contractors, inspectors for roof, foundations, electrical, plumbing, etc to make sure it is not needing too many repairs.From what you have said, it sounds pretty good.

However, I can’t condemn a method of financing that has proved successful in many of not most instances in allowing participants to accomplish their goals because it’s being misused by some disciples of irresponsible real estate “priests”  Sub-To investors are slimier than the towels after a Deshaun Watson massage.

North of town, west of I-5: 95219 Brookside (high end gated communities; Mello Roos school taxes - so high taxes; Lincoln School District; some peat dirt problems on streets; don't know about foundations); Spanos Park West (some gated; lots of huge houses; basically built for commuters just west of I-5; Lodi School District) North of town, east of I-5: 95209 Spanos Park East, Colonial Heights (most Lodi Unified Schools; though small pocket of Lincoln Unified) North of town, east of I-5: 95207 Parkwoods and Lincoln Village (Lincoln Unified Schools; was considered best family area due to Lincoln Schools, but lots of flat tops and built since the 1950s so electrical can be kind of minimal - 1 outlet in kitchen instead of enough to use multiple appliances); lot of remodeling in this area.

One guy did the labor aside from the hvac and electrical.

I like the smaller plug and play option but wondering if anyone has one and how their electric bill has been?

The property was built in 2018 and the other unit with power had no major issues and all HVAC’s, water heaters, electrical, etc all work fine.

One option is to rent out an RV (connect to plumbing and electric) and they live in your driveway. 

Be mindful of the state of the property's general structural integrity as well as the roof, HVAC, plumbing, electrical, and door systems.Create a comprehensive scope of work that describes all the fixes and enhancements that are required.
