It can be very intense and you'll definitely want to just watch the first time to get a feel for it.The trustees and private auctions happen on the north side of the building, the tax sales are on the west side, south side, and interior of the building.When you are ready to buy one, you must do all your work ahead of time and have a FINAL price in mind before the auction begins.

And although the note business can be a capital intensive one, it's also a vast space with many avenues - everything from creating notes or lending money, to buying institutional notes (my area of preference), all the way to P2P Lending.

You can expect a higher quality tenant and higher income, although it is more time intensive. 

Anyway, now I have noise complaints of the other tenants, the police was by to settle disputes, all sorts of fun.

I would say to expect the first two years to be kind of work intensive as he gets this new venture off the ground.

The tenant made a bunch of noise that they were going to counter-sue, but at the end of the day they didn't have the resources to fight it and left.This sounds like a case for the Costa Hawkins declaration that you need to move back into your place, but it sounds like you have already tried that and she asked for too much?

There's just so much information and noise out there that it's hard to figure out how to get started and what steps I need to take first or who to even trust. 

After you have paid it off, with the same intensity, continue to put the money that was going to the debt, into building your savings.

That could get pricey in the aggregate and be time intensive (for the contractor), unless the rehab includes new infrastructure and the contractor is simply warrantying his work.

You must be prepared for something that is management intensive.
