I think it depends on the area and insurance costs.

Capacity and Tolerance. 1) Capacity: how many people can you comfortably fit in the property, is there room to add more, or add more value to the tenants to increase rent.2) Tolerance: How many people are you comfortable living with, if there are vacancies are you able to handle that.House hacking is an amazing path to homeownership, and a nice low barrier to entry into self managing your properties.

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.

I know that if a cost seg, l would need to back that out of my California return.Your answer seems to confirm what I suspected.

I don't think the two unit COA is that bizarre, you either have common areas to maintain via the COA or you have to do cost sharing on all expense by each owner sending in half.

I did not see marketing costs, nights that you need to spend at networking meetings paying for dinners or memberships.

Quote from @Hanna Brown: @Jay Hinrichs If the bidder at the auction pays cash for keys to get the homeowner out, does the person redeeming from the owner position (exercising rights of redemption w/in 180 days) have to reimburse them for those costs they paid to get the homeowner out? 

@Kerry Baird Love hearing about others taking advantage of cost segregation studies.

The current status of the market is low end rentals land lords that let the houses look like crap. 

What marketing strategies are the most cost effective?
