@Josh WillisHouse hacking involves buying a small multi-family property and renting out units to cover mortgages.

An no, there’s no appreciation, these homes are cheaper than they were 30 years ago. 

Then, I am using Rent Property Calculator and mortgage payment to estimate if the property can yield a positive cash flow.

Where these numbers are found, there is a very high rate of rent actually being paid.We have over a dozen Fortune 500 companies just in Metro Detroit with huge Healthcare, Auto, and mortgage industry National footprints.

My thoughts are that if it’s in good enough shape I can sell to a consumer buying with a mortgage company or if needs work sell to an investor for a discount to make a profit.

We chose these properties for cash flow opportunity and because they work nicely for house hacking because the unit you are occupying is a percentage of a smaller mortgage payment.  

Like many businesses, the flipping niche has 3 categories that differentiate one flipper from another: quality, faster, cheaper.

So just curious if my number formula is correct $15k down plus $15k Reno = $30k rental income/year  $14500 vacancy rate 2% operating expensive 35% ( to cover condo fees maintenance insurance ect) $5500 a year mortgage so roughly a 12.25% cash on cash return ? 

You could spend $2,000 a month on a mortgage instead of rent.

I have about 150k equity in my home and have $215k balance on my mortgage.
