The courts here end up overturning these sales on a regular basis, with a simple hearing.

I'm considering buying a property in Tulsa (my hometown) due to low cost of living, having family/friends that I could have check on the property regularly, etc.

If there's something I don't know that goes above and beyond a regular eviction,  and if it's that easy without knowing their whereabouts.  

Typically, you can get a tenant evicted in +-21 daysValid service in Texas is in person, taped to the inside of the door or by certified/regular mail. 

I see two things happening regularly in Nashville: 1 - Houses with a similar or identical floor plan will be mirrored and crammed next to each other on a narrow lot.

If you suspect there is illegal activity going on in the house, you could notify the authorities, REGULARLY!

Like others have said, its a great tool and I also use it daily, but its easy to get wrong to actually perform regular accounting. 

Reputable events are going to at least try to capture the cost of putting them on or to make some money.The Manufactured Housing Institute (which you can Google) is the national trade association that try to protect everyone in the manufactured housing industry in Washington DC and puts out lots of information on a regular basis to those who have either joined directly or through a membership in a state association.Both of the faculty for this event are private consultants.

There are some townhome communities scattered in New Castle County (for instance New Castle &Bear have some around route 7 & 1).If you have someone that is wanting to sell and save listing and marketing costs, you may be able to get a deal together that way.There are also many areas on the City of Wilmington where homes are listed <$50k  pretty regularly.  

The deals you are looking for are definitely out there regularly, especially SFH.
