Six months permit to CO in Ohio is the part worth sitting with, because that timeline is what makes or breaks whether the carry costs stay manageable on the next one. The $9k egress variance is annoying but it is also a fixed cost once it is paid, and the more instructive number is the $14k in holding costs against a six-month build. That is roughly $2,300 a month in carry, which suggests either a construction loan with a rate in the low-to-mid range or a lot of equity cushion keeping the interest bill down. Which structure you used matters a lot for what the second build looks like financially.
The fork most people hit after a clean first ground-up is whether to go back to the same lender on a conventional construction-to-perm or move to a private or hard money draw structure. The construction-to-perm wins when your next lot is already under contract before the build starts, because the lender underwrites the exit at origination and you fold the two closings into one, which saves points and title costs. The draw structure wins when you need to move fast on a lot that will not wait for bank underwriting timelines, or when your next project has a complication, a non-standard floor plan, an unconventional site, anything that makes a bank committee nervous, because private lenders price risk instead of declining it. Given that you navigated a variance on this one, a bank may flag that as precedent on the next application even though you resolved it cleanly. What did the financing look like on the Garfield Heights build, and do you already have a lot identified?
