Trying to help mom retire - seeking vacant land - please help!

[Chris M.]

Hey guys, so a couple things are going on right now: my mom (who is a veteran) is ready to retire in peace but needs help to do so and I currently own a travel trailer and am looking for a place to park it and potentially live in it for a while. Currently in Oregon, I have been on the hunt for a vacant piece of land, from less than 1 acre to 10+, that we can acquire via owner financing with a total price of $10,000 or less. We prefer that this lot of land has power/water/septic already set up. With this lot of land I plan to park my travel trailer on it to live in for a while and also plan on getting my mom a manufactured house to put on the land for her retirement. 

I've been looking on Zillow... but most Oregon vacant lots of land under $10,000 are out in the middle of nowhere with no power/water/septic. Even bought a list from ListSource, but for some reason 90% of the entries are houses even though I specified Property Type Vacant Land. 

My question is: can anyone point me in the right direction? When it comes to searching for vacant land, what do you guys recommend? I am determined to help my mom comfortably retire by next year. Thank you very much to anyone who guides us in the right direction on this.
