What could I do as a landlord if something like this were to happen again - unwanted frequent guests of a roommate...

You'll be completely unprepared for when something unexpected and unwanted happens (which it will).  

The purchase for this post is to shed light on how simple purchasing and selling unwanted rural vacant land can be.I hope this adds something of value to the post for readers.  

I've been doing a ton of co-wholesaling this year or either I've been selling unwanted properties of investors that know I'm a wholesaler and don't want to sell via a realtor.

I read this article on my local business Journal http://www.delawarebusinesstimes.com/charitable-gi...If you know anyone looking to unload an unwanted property please have them reach out to me.

I also have a referral incentive program if you know of any person interested in selling their unwanted property. 

You can make money using an agent, it is just harder to do.......... there are other ways.I am a broker and understand the agent culture........it is an honorable business......it is a lot of hard and long work that agents are involved in.......it is sometimes a thankless job.As investors we need to find the unwanted, unlisted ugly real estate with equity and with motivated sellers; houses, commercial and non-conforming properties to survive in this competitive real estate business.

I do wholesaling as overflow or unwanted inventory, as I do higher volume of deals in bulk I don't want to cherrypick one SFH at a time, but other investors do, so I always know single unit deals that want to be sold, and investors who want in on a unit like that, so I wholesale it to that investor for about 10%.

It saves you from having to deal with a lot of the unwanted responses and having to educate any callers about lease options.  

Maybe they will owner finance any big profit they are making or maybe it's not even on the market and go after those first whcih might now be rental homes, unwanted by the owner who is now stationed far away.
