While I idealize the BRRRR methodology and finding a multi-unit property that I can house hack and create cash flow, the area has a lack of inventory. 

You might see a failing foundation, water intrusion, rotted joists, ancient water / waste lines and who knows how many other red flags.In the attic, I look for knob & tube wiring, missing or insufficient insulation, leaks, crumbling chimneys, etc.To have both of those areas off limits would be an absolute deal breaker for me - and shame on your Realtor, who is supposed to be your fiduciary!

The formula is:P = CF / k-gWhere: P = Price, k = discount rate; g = constant growth rate; and CF = cash flowReal property can be valued using the same methodology.
