How to keep homeless people away from vacant property while I try to sell it?

[Anirudh Reddy]

Hello,

Hello! I am trying to sell a property that i own in dayton, Ohio. I was told that homeless/squatters got access into the building somehow and they were seen by an agent who was touring property for their buyer. How can i stop homeless/squatters occupying my property? 

I don't want to put boarding all over which would reduce my property value which is what my realtor is recommending me, but I am not sure if I am 100% in favor of it. What else can I do instead? Anyone experienced this in past?

Should I just go back to getting the property rented out completely and then market it for sale? Would that be a smart move? 

Thanks,

Ani
