Does the question have anything to do with reg fee vs transfer fee?
What's the lowest transfer price to a FT registrar right now? Assuming around $10?
Vs
What's the lowest reg fee right now? Anything less than $5.96 at Z.com (not FT approved) or $6.99 at porkBun (FT approved)...?
I'd think your answer would be name dependent, and if you plan on dropping or wholesaling the names you don't want to renew.
Sometimes a domain looks appetizing at a $6 reg fee, but the extra $4 the following year for a $10 renewal may feel a little steep depending if I lost or gained interest in that domain after owning it for a year...
I have a 1.5-2% conversion on these names per year,
Can I ask at what sales price point?
If you're selling 1.5-2% for $1,500+, I'd assume that could justify renewals...
If your new regs are the same quality as your renewals, and if funds are limited, you might be better off wholesaling/dropping instead of renewing, and using the new capital on new regs.
But then you're fighting the question, do second/third/fourth year regs sell better than first year regs? ie if a potential buyer is waiting for your domain to drop before making an offer or binning now...
