The cost to maintain them probably wouldn’t be exactly 8x as compared to the single 8-unit, but it sure as hell isn’t a 1-to-1 ratio either. 

I'm very good at running comps and determining rehab costs.

Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover tenant nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620 (approaching 22% probability of default), many blemishes, but should have no evictions in last 2 years.

It also saves you some costs, which is helpful when you’re just starting.

Since you know what you need to buy it at and an average rehab cost, I would say $50-70k for a cosmetic flip, set the ARV based on the sample you choose and doing comps and ask them if they would invest in a deal similar to this. 

Looking to construct a duplex at a reasonable cost but also quality for long term durability.Thank you!

It costs $25. 9am to 11:30am.

To me at my current knowledge level, this deal only works if taking over the loan - to limit the out of pocket money to acquire the property since the outside reno and new septic would take up the bulk of rehab costs. 

A typical PPM will cost about $10K.
