Since contract for deed (when done properly) does not get recorded, nor does a deed get transferred to the purchaser until the contract is fulfilled, you will not have to "foreclose".You will, however probably have to do an 'ejectment' (in simple terms a more complicated eviction) if the purchaser will not voluntarily move out.  

Does anyone have any information or tips on how to file an ejectment, take possession, insure the home etc. 

Hi, On a Tax Deed property purchased from State of Alabama, if I  want the previous owner to redeem do I need to file Ejection Lawsuit prior to his redemption?

I know that an ejectment can cost as much as $2,500 so is it worth it to go up to that to prevent property damage, removal of appliances, etc.?

Translation:  if they mess up, and they know the law, you may have to do an ejectment (similar to a foreclosure) rather than a straight eviction.Lease with option to buy is the way to go. 

Is it better to file for eviction or to file for ejectment?

Am I allowable to eject the current tenants? 

Otherwise, you give written notice to vacate, and then file ejectment.

@Matt N.If this person is a true "squatter" --- meaning you have no landlord-tenant relationship with this person --- you may need to file an ejectment action.

An ejection pump is usually an option if you are downhill from the sewer.
