For the tax liens, that is more of a long term commitment as the state you choose to invest in will very possibly have different laws and time frames as to when you buy the lien and when the lien is either satisfied or you are able to take possession, which is not an easy process. 

@Jane Dang  Here's a notice template for you (it's the one I use in California):60-DAY NOTICE TO TERMINATE MONTH-TO-MONTH TENANCY TO: (tenants' names),AND ALL OTHERS IN POSSESSION of the premises located at: (address of rental property).YOU ARE HEREBY NOTIFIED that effective SIXTY (60) DAYS from the date of service on you of this notice, the periodic tenancy by which you hold possession of the premises is terminated, at which time you are required to vacate and surrender possession of the premises.

Had I possessed the knowledge I have now, I wouldn't have wasted 10 years waiting. 

She can buy the note on the house but she won't be listing the house for sale without taking possession of the property through foreclosure or some other means (deed in lieu, etc).

The typical use of land contracts is to protect the interest of the seller (make it easy and cheap to regain possession of the property in the event of non-payment) with a less than stellar buyer.

But make sure you give the proper notice for September.Take possession, get it sold, chalk it up to a life experience.

They countered at $139,000 and to close on 8/3/18, plus they wanted 3 days' possession so they could move out over that weekend. 

Fannie Mae actually explicitly uses artwork and collectibles as examples of collateral you can borrow against for a down payment, not just real estate, but I've so far not tried to be a smart alec and use a smiley face drawn on a napkin as "artwork" collateral.

I will have to assume all responsibility and liability for any occupancy, and all responsibility, liability and cost of taking possession.

We had the long discussion on BP on adverse possession over it.
