@Sean McKee We were typing at the same time, see my reply above.
To the point of "severe damage" which is most people's arguments, the numbers still usually work better for move-in fees. On the face, one is 1/2 rent while the other is 1.5x rent, yet it being non-refundable makes a huge difference. Let's dig deeper...
If there is damage done, from say 1 tenant/year, he'd get, best case $1,500 SD? (1.5x rent in our example) That'll barely cover a new set of appliances. A single granite/quartz countertop is more than that. You're losing from the first one, how many can you handle before the bank goes bust?
If there is damage done, again from 1 tenant/year, you'd have grossed $6,000 from move-in fees. If no damage is done, you're still getting that though.
Do you not perform a deep clean when the tenant moves out anyway, regardless how clean they leave it? You're paying for that out of pocket. You can't keep that fee from SD if they clean if to a certain degree. If they patched and painted to where it's presetable, yet not up to your taste, how do you charge for this? Hold half the SD because now the whole room or wall needs painting?
It's a ripe opportunity for a sour ending.
Logic tree:
Security Deposit:
Damage done? No? Net zero
Damage done? Yes? Maximum hedge 1.5x rent. Tenant expectation is to return SD and will fight for it.
Move-in:
Damage done? No? Net 1/2 rent
Damage done? Yes? Maximum hedge = (1/2 rent) * (no. of units) Tenant expectation is this is non-refundable.
Equation:
(1/2 rent) * (no. of units) ≥ 1.5x rent
This will always be true at or above 3 units.
More equations: Let's say you net 40% of your gross revenue. Not to pick on @John Warren yet let's keep going with that example...
$1,000/month rent * 12 months * 62 units = $744,000
62 units @ 20% turnover rate = 12.4 units/year * $500 move in fee $6,200 annual move-in fee.
Netting 40% gross revenue of $744,000 is $297,600
$6,200 / $297,000 = 2.1% net revenue increase just by switching to move-in fees.
We can't assume tenants will do less damage because they want their money back. If the person is vetted in all other aspects, $1,500 shouldn't be the motivating factor to be a good or bad tenant.
Either way, one is a hope while actually having very limited upside, the other is a financially sound move for anything over 3 units.
