What Are Apartment Buildings Worth in St. Lucie County, FL?
Apartment buildings in St. Lucie County are trading around $138,000 per unit, based on the recent closed sales I track. On a 24-unit apartment building that is roughly $3,312,000, before adjusting for your actual income and condition. Here is how that number is built and what moves it.
How the number is built
A buyer prices on income. I start with in-place rent, take off vacancy, then rebuild the expenses a lender will underwrite: taxes reset near 80 percent of the new price, insurance on today's replacement cost, management at 10 percent even if you self-manage, plus maintenance and reserves. What is left is net operating income, and at a 7 to 8.5 percent cap that is your value. Older, tighter-run buildings in strong submarkets hold the top of the range.
What moves your number in St. Lucie County
- In-place rents vs market rents.
- Expense load, especially insurance: about $950 a door inland, $1,350 and up on the coast and about $1,500 in South Florida, up from about $400 in 2013, though rates have started coming down.
- Vintage and deferred maintenance.
- Taxes reset at the sale, so today's low tax bill does not carry over.
