Talking with a lender to find out where you land on purchasing power will help narrow your focus to areas likely to yield the best results for your budget.Once you know your number, I am more than happy to share my experience and recommendations.There are lenders on BP who are also investors.

Hopefully the plumbing, electric and A/C are just as good.

I'm closing on a quadplex this week but it's only has two electrical meters.The property currently has tenants in place but the rents are low so I will be raising rents to meet market standards.

Based on your spreadsheet, it looks as though the tenants pay their own electric and gas.

Electric, cable/wi-fi, water etc to make it make more sense and also avoid a more aggressive contract.

I have owned multiple properties with vulnerable areas of plumbing in spaces like this, and having a small electric heater in there is way cheaper than having an issue.

Note that I have absolutely no problem with folks earning what they are worth (hey, power to you!)

@Belinda Mang If you remove an inspection contingency with your offer, you loss any and ALL negotiating power after your inspection findings. 

Basically you should figure to replace all of the mechanical electrical plumbing lot of places are laughing plaster with no insulation true 2x4 construction which is nominal sizing.

One powerful indication of true market value (assuming enough time on market, arms-length buyer, etc.) is the most recent offer / purchase price for a given property.
