@Dyryl BurnettOne of the simplest strategies you can put into play for yourself without any sort of cash to provide upfront, would be to work with a master lease, or a "sandwich" lease.

An outright sale might be the simplest and most cost effective solution; you could do a 1031 exchange into a more profitable rental property perhaps?

Buy and hold locally will probably be simplest route.  

This will defer all of the tax liabilities.Parts of the tax code can be combined to achieve this, but 1031 is the simplest, most straightforward, and can be conducted by any investor (read: accredited status not required.)

Where have you found the simplest and most helpful information related to this?

The simplest way is to get the seller to carry a note, with your 10K down.

The simplest thing is to use a piece of 12 or 14 gauge, uninsulated, solid copper wire. 

Since then this lady has complained about the simplest things and has already did damage to the home(Spray painted the baseboards half way with brown paint which got on the flooring) and we don't know what else since shes mad. 

They can be very helpful though, and they work like this:If the monthly rent is 1% of the purchase price, then it might be a good deal.So for the simplest example, if you can find a $100k house that will rent for $1k/month, that could work.In some markets, like mine, it's even possible to find 2% deals.

For example, say you owned a MFP with many units or an out of state property that you can't or don't check on too frequently and the property manager says there's a vacant unit that they're working on filling but they've secretly rented it out and are pocketing the money from the "empty" rental unit, whats the simplest way to find out whether this sort of thing is occuring?
