You'll need to figure out where to market first. Do a lot of research on strategy, contracts, rent rates, rehab costs, ARV, location, etc. but once you've got an idea of where you want to market, if you are bound and determined to get started in wholesaling with only $1,000 then this is what I would do...
BTW, this is basically what I did and I how I got started in Memphis
$10 domain name from GoDaddy. You DO NOT need a website, just the domain name so you can get a proper email address. Something like TomJ_at_webuyillinoishouses_dot_com
$10 business card from Vistaprint. Simple "We Buy Houses Fast" with your name, phone number, and email address.
$500 for 1,000 stamps
$200 for 1,000 names/address from Listsource
$25 for 2 X 12 packs of yellow pads. 50 pages per pad from OfficeDepot
$30 for 1000 envelopes from OfficeDepot
$12 for Pilot G-2 pens from OfficeDepot
This is only $787, keep the remaining $223 in a bank account for right now.
Send out 25 yellow letters a day, everyday, for one month. DO NOT send them all out at once. You'll be overwhelmed with calls, then they'll dry up. This way, they start trickling in.
Out of 1,000 letters, you'll likely get 100 phone calls. Talk to 100 people and go look at 10 properties. Make offers on all 10. Get 1 accepted. Assign the contract for $3K-$5K and you're off and running. If for some reason it takes a little longer to find / close on the first deal, you've still got the remaining $223 to fund another week's worth of mailers. Keep putting properties/leads in your pipeline. Don't wait for something to close before you start investing in marketing again. Let me know if you have any questions.
