I have put nearly $`13,000 in electrical  rewiring of both units, painting, new ceiling fans, and a new hot water boiler for the un-rented unit.

I have a specific question about pulling electrical permit.

James and Shanti Its not that expensive because you have the ventilation in place and the electricity.  

I wouldn't go so far as all of those special sound proofing underlayments and overlayments, just extra insulation and it will keep the noise to a minimum.Given the age of the building - electrical is my big recommendation.

In my area electric cars are really getting popular.

Does the electrical service have capacity to add condenser and AHU or does it need to be upgraded? 

Enter new to home buying guy and wife looking to buy a home in San Antonio to live in then rent out.Home listed for $220k it was a flip and was purchased for $60k less than a year ago.Exterior looks wonderful, inside looks great.Original 100yr+ hardwood floors, everything looks very shiny.As we are walking around we start flipping switches, flushing toilets etc.One toilet in particular makes a very gurgly sound that doesn’t seem right and some hall lights don’t work.Our RE agent is all about telling us to hire a General Inspector which will cost about $400 to inspect the property and tell us if anything needs to be fixed.As we look around we start to see more problems.There is a place in the roof where the roof has raised away from the house leaving a sizeable hole to the attic.There is no drip edge along the roof.The breaker box has empty slots in it that let us see into the drywall.Knowing this was a flip we investigated on another Texas State website to look at all the filed permits for the new electrical, plumbing, HVAC, and roofing, and got nothing.No permits filed at that house.Red flag?

Due diligence revealed that the place needed a serious rehab (roof, toilets, electrical, flooring etc.).

Either through signed leases or by contacting your local utility company to check the electric bill, the oil bill, water, sewerage, etc.This will give you your income (rents), monthly payment (piti), and monthly expenses.
