It does happen and although tax liens can be a passive investment it is good to learn the rules of the state so it doesn't sneak up on you causing you to lose everything. 

It was funny though cause my wife was disgusted by it but I just laughed and started putting in the new windows I bought.

Combined with great branding, those multiple touches cause people to remember you over time, so they think of you when the need arises in their life.  

@Leo B.So as a rough guide (cause you'll want to factor in things like depreciation you have to recapture, capital expenses over time, costs of sale etc) if you bought for 400 and sold for 500 then you have 100K in profit.  

Things get damaged, so there is the dealing with repairs/replacement of items.

You did this when you piled on the complexities of another child and renting your current house out - which to me is when you should be working 10X as hard to ensure that this situation doesn't cause you more stress.As for the lead time for documents.  

Special assessments can pop up and cause economic hardships and create liens that the Borrower or Mortgagee may have to deal with. 

Obamacare is causing problems as they are nickel and diming the doctor's office.

And causes you to have to pay the tax on unrecaptured depreciation.  

What damage and other things should I look for to consider should I decide to make an offer?
