@Derrick, I grew up in the Delta.

My best friend just got a job flying for a Delta airlines affiliate out of LAX.

This allows you to make the delta between the two interest rates and owner finance without the responsibilities and unexpected expenses of home ownership.

(from atlanta on delta) So we'd be happy to share.

One thing I used to do when just staring out is at the end of every day I would do "Plus" "Delta's" .

Maybe the small delta in typical scenarios is why people tend to not worry about it too much.

Estimating Delta's on seasons and tenant moves will no doubt provide a use of your time, but probably not Highest & Best Use of a most valuable asset.Either-Way, The Tenant Must Pay ;-)

Our biggest delta was 10% over quotes/estimates for a 'traditional' rehab w/o any efficiency improvements - but this was a 120 yr-old ballon-framed house that registered 12 AEH prior to retrofit (~4 AEH post retrofit ... which is still huge compared to modern passive hause, but we were warned not to make these old houses too tight as they tend to develop mould and air-quality issues).Since our properties are all buy-and-hold (at this point), the operational benefits of an extra 10% cost to a deep retrofit/renovation are easily paid back in <3yrs.

@Scot Finn two cents...have you considered the delta between the values of rehab and rehab + new construction relative to the market based ARV?

I flew from Nashville to Tx to LAX with Delta on Nov 18 and then back Nov 23 with a direct AA flight.
