Also, more room in the electrical panel if you need to add A/C or some other circuits now required by code and avoid an entire service upgrade.Good luck to you,Gary

Not a deal breaker necessarily, but a risk to be aware of and mitigate.2.

Electrical Panel - Sometimes these are located outside you can you take the panel off to see if the breakers and wire are up to code.4.

Basic tool and power tool safety, including ladder safety; fundamental electrical questions such as what size breaker/fuse should you use on a circuit with 14 gauge wiring; where should GFCI's be installed; how to check for hot conductor; etc.

A tenant has an electrical circuit that goes dead.

We corrected that by throwing the breaker which may have tripped when there was water (like it was supposed to).

Roof, driveway, garage door, minor garage repair, furnace, windows, floors, kitchen, bathroom repairs, paint, electrical panel upgrade and all plugs are 2=prong, more circuits ran to the kitchen for electrical upgrade purposes, the plumbing is galvanized and needs to be updated to copper to pass inspection. 

This wouldn't necessarily be a deal breaker, but I would definitely ask for the tax return.Let's see if @J Scott has anything to say here :)He has had this type of income in the past ...I would ask for tax returns...if he's a true professional, he reports his income and it's verifiable. 

The rate reduction was only going to be ~$140/$100k assessed, so shouldn't be a deal breaker in evaluating properties.

They can and most often are a PIA and a deal breaker.
