My 3 unit in Albany brings in about 1500 a month in free cash after budgeting for debt services, maintenance, and reserves. That's approximately 170/door. This is also because I'm paying down a HELOC from that income, but without the HELOC payment involved I'd be bringing in close to 250/ door. I manage it myself.
Im on the lower end for sure, especially in Albany but student housing prices are sky rocketing to over 250k. Based on that my house was a steal at 203k for a rare 3 unit. One of the 3 units has potential to be higher rent, but that tenant has been there for 10 years so weighing the costs of giving her the boot and rehab, letting her stay made more sense financially.
The way I look at it is, does it provide me positive cash flow of at least 20%? If yes I'm inclined, if not then is there potential to achieve that? If yes I'll consider it, if not then I move on. I currently get a 25% cash flow after paying heloc, debt services and maintenance such as garbage and water. I pay utilities for one of the floors but others they pay their own.
