There used to be a few bay area BPers, but most have disappeared over the years.Bay area, IMO, is the best RE investment market in US.

No spreading it over time; that is just inviting them to disappear owing money, and leaving possible damage in excess of anything you have collected to date.Look at it this way.

I have a lot of nude paintings that have disappeared from my places. 

It's not really comparable since the housing market would take months to crash and bitcoin could crash in a few hours....And for everyone of these anti bitcoin guys saying it's tulips or emus or a ponzi scheme and "if you buy bitcoin you will lose your money" I say maybe if you sell when it's lower but these same people were saying the same thing when it hit 300$ and 600$ and 1200$ and then when it dropped to 170$ in 2014 plenty of peope saying I told you so I told so but if you bought in and held on still seems like it would have worked out ... now that said full disclosure I own no bitcoin and do believe it will crash just don't think it will disappear or ever be worth less than 2000$ a coin and if you'e reading this in the future pm or tag me to show how wrong I was lol..

Also, Bitcoin can't be "hacked" but the exchanges can and value can disappear or be stolen.

Then they see a 50% ARV offer pop up in their inbox or mailbox and all that rapport disappears. 3.5) What I do when sellers call me is I ask about their situation, their property, and then I tell them I'd get back to them later in the day with a range of what we might be able to do, and I always say if we are even in the same ballpark then we would love to come take a look at the house.

Both of these are more "abrupt" in my opinion.

Property taxes don’t go down or magically disappear when the economy tanks .

After the packages keep disappearing she will get the hint. 

One of the best deals I purchased was a house that was originally tied up by a "wholesaler" that disappeared after holding the seller in limbo for weeks!
