If you do close then you are legally bound to perform is that is what you agreed.Your deal is a lucky one but the mechanics of the transaction is not that uncommon.

Sorry, don't know the mechanics, and haven't done one of these transactions, so I'm not sure how to coordinate it.

I have been supplementing my unstable commission based income with mechanical side work and snowplowing.

Realistically you need to look at the mechanicals to have an idea of what your big ticket items will be.    

@Josh Corby you're very welcome.I, personally, have never purchased sub2 or seller financing but they're both fairly straight forward in terms of the mechanics of the deal.

Maybe some smarter minds than me could come up with a "2%" rule for the Bay Area - something that concentrates around cash flow with an emphasis in the appreciation game. 

We have also closed a deal and sold off a portion which was not of interest to us - the closest we have been to a "skip transfer".There is generally nothing wrong - legally - with the transactional mechanics of buying a property than {almost} immediately selling all or part of it.  

Each house and each neighborhood is different.I automatically fill in x cost for mechanicals (electric, plumbing HVAC... etc) per sq foot.

Anything mechanical is off limits.

If so we cashflow 845 a month                     When we take a loan against it for 100k and use the 20k down we pay 735 a month and cashflow 465 a month until he buys it from us.The rest of the story:He is a mechanic and this is on a major highway so he operate the business from here.
