In addition to frequency of transactions, the IRS would evaluate whether the activity is executed in a fashion similar to commercial enterprises in the same field.  

Then compare the frequency of reviews to an area that you know has high demand.

@William thank you for the explanation.I just see this term used a lot more frequency and can't help being curious.I speculated what could have prompted that too and the only scenerios I could come up with is a trailer home being hauled out, or something like erosion, where a landslide eliminated a significant portion of the land, or a hurricane hitting the beach and took out some parts of beach front land...something crazy like that.In the case you mentioned, someone actually moved a house?

When determining whether services performed by a corporate officer are considered nominal or minor, IRS agents examine the character of the service, the frequency and duration of the performance, and the actual or potential importance or necessity of the services in relation to the conduct of the corporation's business.Example: The officer of the corporation perform only minor ministerial functions entailing a few hours work a year for the corporations.

I am not sure why it happens, but the frequency is high enough that I assure you it is not a coincidence.One reason you can see multiple offers is because one offer attracts another.

If I were in your position, I would look at hard data on lot sale prices and frequency of lot sales in your area.

Poor people are looking for freebees and may increase your frequency of tenants not paying on time.3. 

Also, How many/at what frequency have you done follow ups to your pre-foreclosure.

As much as I am trying to break into the 40+ unit complexes, it just works out that I can only afford smaller units due to the frequency of my purchases. 

Nowadays, there's so much competition with the institutions using high-frequency software, the individual investors like me also have to use high-frequency software, or we won't get any loans.But it is an awesome model and an amazing financial innovation.
