Often wholesalers and investors cross paths in these communities.3.Direct Outreach & Marketing:Consider running targeted ads or direct mail campaigns focused on property owners.

Nature campaigns, direct mail, text services, accounting, etc all in one place.

The BRRRR method (Buy, Rehab, Rent, Refinance, Repeat) could also be a great strategy to recycle your capital.To find deals, try direct mail campaigns targeting absentee owners or distressed properties, or go driving for dollars in neighborhoods with strong rental potential.

Zoho Campaigns, this is to send out emails similar to Constant Contact.

Focus on driving for dollars during free time, and set up automated mail campaigns to keep leads flowing.

You can target lists through a multiple list source sites, skip trace those lists, then market to those buyers through cold calling, SMS campaigns, direct mailers, and/or door knocking; amongst other routes.
