If the home is 100 yrs old, I'm assuming it's a definite gut which is going to require new plumbing, electrical, heating, cosmetics.I spent about $140K reno on my multi family in the heights on NY ave and there were massive problems with it but it was a gut to 3 units & adding 2 bathrooms, 3 brand new kitchens 4 bathroom reno in total, all new flooring, sheetrock , insulation, framing, doors, electrical, plumbing, paint, parts of roof etc.

In the Parlor floor we added a large-ish kitchen with electric oven and cooktop that goes to the sub-panel that belongs to the Parlor floor, making it a nice 800ft 1 bedroom apt, with access to a shared backyard.   

@Dean Malka 10k for average kitchen and 5k for average bathroom Flooring is $4 a square foot for LVP HVAC $5k Electrical panel $2k.This is all ball park.

Wow, this is powerful.

If your land can sustain a data center (power requirements are huge) then the land would sell for a pretty penny.

I have been playing the multifamily game for almost 10 years now, and the GRM is one of my least favorite methods personally since it ignores so many important factors (steam boiler versus electric baseboard heat as an example). 

If you do it more power to you.

Inspection was schedule for today but when the inspector / my realtor arrive the power is off. 

We focus on CapEX before beauty. as a realtor we understand selling or renting homes you have to make the home function, Roofing, windows, electrical and plumbing. after we address these we focused on beautify making sure the upgrades match the area and is forward thinking with color scheme, flooring, and flow.

The office has an A/C window unit with drywall, carpet and electricity.
