I'm out of town until November 4th as well. 

Home was built in 1960 with minimal upgrades over the years How did you finance this deal?

This is a general guideline but it will differ a little by area.A - new construction with amenities in best area of town, often where professionals and wealthy people liveB - good neighborhoods where middle income live, generally house will be older but well maintained and few subsidized properties C - lower income, mostly rentals, a lot of subsidized like section 8, etcD - dangerous, graffiti, drugs, boarded up propertiesYou won’t find all classes in all areas.

I also have looked around on rents and a homes between that size pretty much all across town are 1000-1300.

I was out of town on a 15 day back country trip with no cell coverage so wife was forced to deal with this solo.  

Will I be able to place a mobile or stick-built home on the property without any issues or sell it for a profit?

I recently purchased a list from listsource,  I selected 3 local towns close to where I live. 

You could be missing out on a lot of deals if you are using 50% for expenses and most places in your market are operating at much lower.Also, if you have built a relationship with mortgage broker, you can send them a deal you are working to get more accurate # as well.

In one town regardless of what the lease says.

Bought a single screen theater in a small town and flipped it a year later for 50x.
