They can simply continue their negotiations, or sue each other.If the mortgage was originated on or after January 1, 2016, then everything above is the same EXCEPT for the time limits for redemption.  

As just a few small examples:You can "flip" a stock that is undervalued (except instead of hiring contractors to improve the property, you're relying on your assessment of management's ability to do so).

We did that on a few properties and you can't tell a bit of difference except about 1/2" of ceiling height. 

@John Jacobs exceptions are written into the Dodd-Frank act to accommodate owner financed transactions.  

One of the units of the building I was interested in was "rented" by the owner's son who obviously didn't occupy the unit as it had no stove or refrigerator and lacked furniture except for a bed.

@Ken YuYou should not be putting any money down as an earnest money deposit so the only money so you should not be losing money in bringing a deal under contract except for the time cost. 

I'm fairly new to this...except I have owned and rented a few mobile homes several years ago but this is my first attempt at making a viable income with reasonable skin in the game.

Much of it is just plain wrong and exposes their followers to all sorts of legal problems for heeding their bad advice.Just yesterday, another BPer asked about starting up a property management business and pointed me to a website that insists that property managers need no real estate license in MA.I spent a few minutes of searching and came up with a link to MA state law that says there are only three exception - the property owner, a salaried employee of the property owner and a hotel reservation worker. 

Now that I think about it, I can not think of a single question I would ask a BUYER, with the exception of: prove you can buy it, and when do we close.Their business does not matter to me.
