step 1 - area, size, purchase price in your range (all that research). Spend a full day on this.
The rest of this can be done on a Sunday afternoon:
step 2 - pull a list of exact sellers you want to mail to. For example, 3/2, zip code xxxxx, subdivision, lot size x, assessed value between x-y, no mortgage or less than x %, etc. You download a report in an easy spreadsheet with owner name, address, and all property detail.
step 3 - scrub your list to remove duplicate owners, government agencies, anything out of ordinary
step 4 - "mail merge" list into your ready to go offer letter to purchase. (make a sincere, realistic offer and included your closing agenda)
step 5 - use a cheap, industry specific printer (we spend less than the price of a stamp to get the whole thing printed and mailed)
step 6 - wait for signed offers to come back and pick the best ones to purchase! Or put them under contract and pass the deal to your ready to go flipper and charge them $10k per deal like we do.
You should be buying at way less than "market value" so everybody wins! Hope this helps.
