Welcome to BP community Denise S.  It

They don't have to, someone else with experience will buy the lot without having to do much due diligence.But a parcel with unknown development rules that has been sitting for a while?

If she doesn't want to transfer the whole property to your sister, I don't recall your mentioning what kind of property it was, she could transfer it to a new trust or LLC and sell part of that to your sister and then your sister might be able to pursue a loan.I would also talk with a local banker about refinancing some of your mom's high rate debt, just that might free up some cash-flow and that always helps.As a last resort you mom might have to sell some property to get funds to bring the the remaining holdings on line and up t speed.  

I've listened to every BP podcast and am having trouble recalling a specific one...The guest...Worked full timeHad a partnerRamped up his REI business very quickly to 20 + in less than a year (if I remember correctly).He also began aquiring other types of business...

You sit on it for a couple of years (collecting rents) or do you take your profits, and roll them into several other projects like this current one. 

I would be interested to learn about whether Patrick H. is involved in a project or sitting tight.

Lets say you are sitting on auction and you entered the winning bid.

of all the turnkey people on BP I have talked to ,none have the property done and sitting there to sell.
