How much Direct Mail & One flip or Multiple at a time with cash?

[Darlene Bush]

Hello BP!

I am new to this site and Real Estate Investing in general. I have always wanted to do this so I am going to give it a go.

I am going to start a direct mail campaign in January, targeting 2500 homes a month with yellow letters. Hopefully this will turn up some some good leads on houses. 

Should I do more than 2500 a month to get enough leads? 

I have 500k in cash to use. I am looking for houses in the 200-250k range. 

My question is, if you were in my position with the cash. Would you use the cash for one house to rehab and sell at a time OR would you do multiple homes with hard money loans? 

Thanks for any advice offered.
