Market Trend Direction - When To Buy\Hold And When To Flip

[Daniel Highsmith]

I'm selecting a Farm Area to send direct mail to. I have two areas that i'm comfortable with. After some initial research on Trulia i can see the median sales price for Area A is trending down

Area B median sales prices are trending up over the year

My question is this: Should i target the down trending market for a possible low priced buy\hold rental? Or should i target the upward trending market for a possible "buy low, sell high" flip opportunity?

I plan on getting a listsource list (possibly absentee owners) and sending to one of these markets on a monthly basis. Any info is much appreciated! Thanks, BP Community!
