Convert the subscriptions into cost per accepted lead or the number means nothing. At $250 a month of tools and 10 accepted leads, you're at $25 per accepted lead before your time. At 30 accepted, you're at $8. The fixed cost is trivial and it stays trivial, which tells you subscriptions are never the thing to optimize.
Your hours are the cost. A three-hour route covering 120 houses might flag 15 worth researching, of which maybe 6 skip trace cleanly and 2 are worth submitting. That's roughly 90 minutes of desk work behind every drive. Price your offer against that total, not against the drive.
Given you're on the renovation side, your edge is condition assessment, and that's the part buyers pay a premium for. A lead that says "1970s roof, two layers, visible deck sag at the rear" is a different product from an address. Sell the assessment.
Where this bites people with your background: you'll be tempted to submit properties you'd want yourself, and then you're feeding your own competition or holding leads too long deciding. Pick a rule in advance about which properties go out and which you keep, or the good ones sit in a folder while you think.
Bulk skip tracing at pennies gives you phone numbers with maybe a 40% to 60% connect rate depending on the vintage of the data, and that's a bigger driver of your workload than any subscription line. Test two vendors on the same 100 records before committing to either.
