@Josh Shaw  the assumptions on the sheet are a little off in my opinion, for example vacancy is assuming less than 1 unit empty per month, the average complex tenant stays 1-1.5 years, so you can plan for a unit always being empty, so if rent is $650 (as advertised) plus utilities for the vacant unit will be more like $800. also your rehab cost seems quite low, also capX based on what the property looks like from ext, and int photos on-line, it appears to have been built in the 90's so it will need rehabs in the next 10 years, and you need to set aside for a roof, on a building that size its a huge expense.

My expectations are realistic I think, I am making assumptions based off of the previous owner's (of 35 years) figures and occupancy.

Correct me if i'm wrong in that assumption. 

Cheers...Why is it that there is always the assumption that appreciation always comes inexorably tied to negative cash flow?

I've always made the assumption that I should buy a twinhome where I could own both sides of the twinhome, but I'm asking myself to justify owning both sides over either a single side of a twinhome or a single family home. 

I am going to make an assumption.  

Hi, I'm new to BP and have been reading about house hacking on the site, using the calculators, etc.When I use the rental property calculators with the assumptions below, most properties in my area cash flow negative after servicing the mortgage.

I don’t really know that neighborhood over there – your assumption seems reasonable for students.

looking at your assumption for taxes and insurance it seems quite light.

This is a dangerous assumption.
