First off - none of those kinds of properties exist in the areas I'm used to.

@Mack Bailey Sounds like you don't fully understand what a subject-to existing lien transaction is.

We live in a regulated market.

I am also leveraging them for repairs/issues with existing tenants that cannot wait until the rehab....and they generally take care of the property and watch over a lot of things. 

Hard part is making sure you can improve/add to the existing property or a development is more ideal. 

This is adjusted for growth to avoid existing owners getting massively higher tax bills YoY (again, in theory)FL = disclosure state i.e. tax % * price you paidSome other states = limit growth by a certain %Best bet: consult the local tax assessor's office and/or your broker.

@Simon W. right now it is none existent. 

The model is here to stay, but regulations, margins and even platforms may change.

The county is going to be the one with the information, other lists may exist but the county is responsible for collecting the taxes so they should be the most accurate

If you can save up (and possibly borrow from/partner with friends or family) to buy a 2-4 unit property that's rentable in its existing condition, you can live in and fix up one unit while the others are rented out.
