Direct mail to vacation rental owners, has anyone done it?

[Jake Hartman]

My wife and I are interested in buying a vacation rental and have identified the exact area and complex we would like to buy in.  Unfortunately the units for sale don't meet our needs or aren't in an idea location in the complex to maximize rental income.

Being familiar with wholesaling and researching real estate I have compiled a list of approximately 50 properties with owners names and addresses that are in the buildings we would be interested in buying in.

I plan on mailing everyone on the list something to the tune of "We are interested in buying in your building etc etc... please contact us if you are interested in selling or keep our number in case you ever do decide to sell".

My question to the group is this... how would you word your letter?  These will be typed up and signed but the envelopes will be handwritten.  I am fishing and want to make sure I am not offensive nor bothersome, though I know regardless I will rub someone wrong...oh well.  

Any suggestions for how you might word this to encourage at least response from some would be greatly appreciated!

Thanks,

Jake
