I have been looking around online and found places like property shark, foreclosures.com, speedmonster, etc...I just wanted to know if these sites are any good and has anyone had luck with them or other resources.

(Just a bunch of sales pitches and sharks looking to take advantage of new investors.)

You may not have the experience to recognize the Sharks that will start circling you so tread lightly.  

The cost is 168k It rents for 189 a night 1,100sqft Marina slot and fee is 200 a month.

Or half way through your repair, you need to go get an extra part, what do you do with the pile of screws on the countertop, or the drill, or a razor blade on the floor? 

As a professional programmer, I just can't place any trust in ANY online auction system, just like I would rather sit a a poker table than in front a poker slot machine.I was going to cite some examples, but having raised the question of manipulation should be sufficient to cause a moment of reflection before you dive into the deep end of the pool.Your experiences?

Make sure you don't need that cash flow as the margins are razor thin as is.

As mentioned, I have an elderly buyer who walked into a broker (in this case shark) to get info on how to write a contract to purchase FSBO.  

And people are swarming like locusts to bid up the prices of anything that sounds like a wholesale deal.It just feels like behavior and terms that to me signal we are getting close to the top of the market.Nah.....I will pass and work with someone who isnt trying to create some sort of shark feeding frenzy for at best marginal deals.  

Now a spouse has a few freed slots.
