Assume 50% overhead, and use that as your working NOI.
Anything else and you’re turning this into a non-profit, if not a gamble.
The seller may actually have a low/no vacancy rate. This is not uncommon for someone who’s owned property for a while. They get lazy about raising rents, because it actually requires attention to keep units at retail, and marketable. Retail-paying tenants want stuff fixed…
All that said, you know the owner wants out, because she’s too old to manage low-end units.
I’m betting she would love to maintain the income, if she didn’t also have to manage…
You might consider offering her the NOI she’s getting now, which for our discussion would hover around $10,800 less current debt service.
Assuming the cash flow was $4000, you would offer her that amount on an annual basis in return for 100% financing.
She won’t do better than that, no matter what other options she’s considering…
Meantime, the upside for you is, no large cash outlays, and significant rent increases. I’m betting her rents are $50-75 under retail per unit.
$50 x 15units = $750/mo new cash flow to you, or $9,000 pre-tax annually.
The issue is, if you take title, the taxes will go up. If you were to offer the seller a Master Lease, coupled with an option to buy, the taxes, insurance, etc. would stay the same.
HOWEVER, a verifiable, increase in the NOI would theoretically add at least $100,000 to the value of the property, depending on what the market cap is for your area.
Now, this valuation doesn’t apply to single family/duplex/triplex structures. Those values are determined by comparable sale prices, not income. However, the four-plexe’s value will be affected by a larger NOI.
So, once you’ve increased the NOI, the value goes up by $100,000 on paper, and perhaps you could borrow enough to pay off the seller, without coming out of pocket at all. (You would have to do some more homework to prove this was true).
If the seller’s original price isn’t much different than your price, a plain, old seller financing option might be the way to go.
If you frame the 100% seller financing option as an “annuity” style payment arrangement, it will appear much more attractive to a retiree. The ‘best’ annuities, are the ones that go the longest, not the shortest.
So, a 30-year annuity-style payment arrangement sounds terrific. That, instead of ‘you’re gonna finance me for thirty years.’
Anyway those are some thoughts that come to mind regarding 100% financing.
