I probably can get 1500-1800 per month rent for a 3 bedroom, 2 bath (appx 1200 square feet) and can build for 174,500.

I have been sent countless deals from wholesalers in Kenmore, West Akron/Highland square but it seems like at least Kenmore is hit or miss.

Please note i did not invest with them, but wanted to mention that as there are names out there when mentioned its an automatic red flag.

Too much red, too much equity that could be used better.

This single-family residence spans approximately 4,250 square feet and features 5 bedrooms and 5 bathrooms.

Constructed in 1910, this property features a total of 2,793 square feet of living space.

Nonetheless if you can build a 7 plex for $700K (in my area, things are getting built for $200-300 a square foot), it definitely seems like a profitable endeavor. 

Built in 1961, this residence offers 4 bedrooms and 2 bathrooms within approximately 1,500 square feet of living space.

I talked to a modular home company in my area, and he said to build a 4 / 2.5 2200 square foot home would be 215k, and then foundation and utilities would be another 160k.

I've seen estimates of $200 to $400 per square foot for SoCal with $700 sq ft for something higher end and building up a hill and but possibly higher for San Francisco Bay Area (lhigher labor costs, etc.).
