1st Campaign 1000 Leads 1 phonecall, 1 offer. Remail or new list?

[Eric H.]

Context: As stated in the title I recently ran my first direct mail campaign of 1000 postcards here in San Antonio Texas. I got 1 phone call I did go out and make an offer on the house. It was an inherited home with $0 owed and an ARV of $60,000 in a rental neighborhood (comp rent $800 - $900), the prior tenant set the garage on fire. I offered $28k but the owner had an offer from Money Bug for $40k. Seeing as how I had spent some time with him and I found out he was only expecting about $25k before he got the $40k offer, I gave him the "give the little guy a shot" pitch but to no avail.

Question: With a .1% response rate should I remail this list (custom selection aimed at age and equity from PsPrint) or should I get a new list from a new source?

P.S.: I wasn't sure if this post should go under wholesaling or marketing so I just picked one
