A month of inventory is how many houses are selling each month under current market conditions.

I've found that might be a little too much, but I'm not inclined to change it right now. 6% might be pretty much on target, but it does depend on the location (some areas simply have harsher conditions and also might be more expensive for repairs) and the age and condition of the property.

I recently heard a podcast of a gentleman in Alabama who is buying tax liens, fixing up the properties to livable condition and renting out the properties. 

In doing so I have been cursed at, referred to as a slumlord, physically threatened and assaulted.

The roof is at the end of its life so in the next year or two we will have to spend another $8,000+ on a new one.

In terms of the funding options for your next deal:1) if you have IRA (Roth or Rollover) consider SDIRA.2) if you have your own business, consider solo401k. you might be able to move Rollover IRA funds into it. also, a better option than #1 above from a taxes perspective3) partner up with money partner4) look into leveraging your personal life insurance policy as a loan (if you don't have one, go get it)5) you can borrow against your 401k at work up to $50k. you pay interest and all back to yourself

It wasn't a brand new vehicle, but in great condition and probably only a few years old.
