Well, here is a totally different perspective.
As others have said you have to identify your goals. If I had $100k to invest, I would start an automated marketing machine. I am starting this on a smaller scale now, but am planning to scale up. For about $2k a month, you should be able to get deals rolling in.
When you find deals, you can then either JV or wholesale the deal to another investor.
There are several different target audiences to mail to, absentee owners, burned out landlords, etc. The key is to do it on a consistent basis.
If you spent $2k a month mailing to about 3000 people (targeted audience) for 1 year, you will spend $24,000. You should be able to get at least 2 deals where you make $18k each, that should not be difficult targeting the right audience, in your area. Your return on investment would be 50%.
This should not take that much of your time, if you set it up like I recommend, then you only talk to motivated sellers.
Here is how I recommend setting it up:
1) Automate the hand addressing of letters. If you google "hand address letters" you can find several companies that will hand address letters for you. Typically, they charge about $.25 for the service, on top of the postage & printing costs. They make it easy, just email them a word doc for the letter and spreadsheet for the list. They will take cae of the rest.
2) set up a call center. This can be done pretty cheap. I am using one now that I pay $25 a month, plus $0.80 a minute. You just provide the call center with a list of questions, then once they get a call, they collect the info.
3) when you get a message from the call center, call the person back and get more details, the key piece of info being, when do they NEED to sell, if they reply they don't NEED to sell, then they are not motivated.
Doing it this way, you should only be spending a few hours a week.
I would focus on your local area, that way when someone calls, you already are somewhat familiar with the area.
The key is consistency. You must commit for several months. You cannot just try one mailing, saying, "oh, I did not get any call backs, I guess it didn't work".
For further details I would recommend reading articles in the BP articles and blog area. You can find more info there are target audiences and sample letters, etc.
Just my two cents,
