We have an opportunity coming up from a family member who is willing to sell us my childhood home for what they got it for (240k) and the comps in that neighborhood are 600k+.

What do the comps look like?

It's also easier to isolate and manage tenants, because they don't have any affect on each other as they do in MFH.

It’s temporarily lost its shine because of the slow down in transactions.

It's no guarantee but it's a good place to start.

I think our best client in the last 4 years we probably made them $750,000.Then I get the call from the one property owner trying to nickel and dime me that we will charge $190 for his townhome and he can get someone else to do it for $125.

I have heard the 16% solution mentioned. 

I was hoping to do a new construction Duplex.

It's common practice to stock enough for a few days, as you've been doing, and let guests purchase more if needed for longer stays.

This might sound rude (it isn't meant to be), but it makes no difference to me whether someone decides to do it or not.
