Most landlords focus on the rent price. The ones who do best focus on everything around it, because that's where the returns are.

I say that as someone who works both sides of it. In April 2024 I leased 1745 SW 10th Street, a 1926 Shenandoah-plat house, at $13,900 a month to an excellent tenant. That is the highest closed lease on record for a house in ZIP 33135: the next highest is $9,500. I've handled the leasing on that property since the purchase in 2022 and placed tenants there three times.

I also rented out my own South Beach condo recently: a building price record, four days of vacancy, and a tenant I'm glad to have.

Neither result came from asking for a big number. They came from the five things below.

1. They price to the market. Vacancy is the most expensive cost a landlord has.

Holding out for $7,800 on a $7,500 unit gains you $3,600 over a year. One vacant month costs $7,500. The extra $300 has to land within two weeks to be worth chasing, and it rarely does.

The asking rent feels like the decision. It isn't. Time on market is the decision, and every week of it is priced in whether you count it or not.

2. They tighten the lease. That's where the leverage is.

  • Renter's insurance, required.
  • Early termination carries a real cost.
  • No committing to a renewal price with a new tenant, unless it's an increase.
  • At least 60 days' notice to vacate.

Thirty days' notice means marketing an occupied unit against a tight deadline. Sixty means marketing it on your schedule. That's usually the difference between a clean handoff and a vacant month.

None of these four terms cost anything to include. All of them are expensive to be without.

3. They don't delay maintenance. It turns into vacancy.

A small leak becomes mold, but the repair isn't the real cost. Unresolved issues are one of the top reasons a good tenant doesn't renew or even cancels early, and then you're paying for both.

4. They know both numbers: rent and sale value.

They move independently, and most owners track only one. That's how people renew in a year they should have sold. The renewal decision and the sell decision are the same decision from two sides.

This matters more in the Coral Way corridor than in most Miami neighborhoods, because the zoning layer moves both numbers at once. A property that turns out to be zoned for two-family use is worth more as a sale and more as a rental, and plenty of owners here don't know which one they hold. I've written separately about the corridor's T3-O/T3-R zoning patchwork and why the listing description is not the last word on it.

When a rental is working well, that's also the moment to look at buying another one in the area and leveraging the value of the one you have.

5. They buy where easy upgrades earn a premium.

Think of a washer and dryer in a 1960s South Beach condo where most units don't have one. Smart home features. A pool. The upgrade isn't as valuable on its own. It's valuable because of how it differentiates the home from everything else a tenant is looking at that week.

That makes it a buying decision more than a renovation decision.

FAQ

What is the most expensive mistake a Miami landlord makes?

Overpricing the rent and absorbing vacancy to defend it. On a $7,500 unit, a $300 monthly increase is worth $3,600 over a year, while a single vacant month costs $7,500. The increase has to be leased within about two weeks to come out ahead.

How much notice should a Miami lease require before a tenant vacates?

At least 60 days. Thirty days forces you to market an occupied unit against a tight deadline; 60 lets you market it on your own schedule, which is usually the difference between a clean handoff and a vacant month.

Should I lower the rent to keep a good tenant at renewal?

Keep the good tenant, but don't pre-commit a renewal price to an incoming tenant at signing unless it's an increase. A promise made a year early gives away your ability to respond to a market you can't see yet.

Do you work with landlords in Shenandoah and the Coral Way corridor?

Yes. I've handled leasing on a Shenandoah-area property since 2022, placing tenants three times, including an April 2024 lease at $13,900 a month, and I represent buyers and sellers across the corridor. My full corridor track record, with MLS numbers, is at /about.

If you own a rental here, I'm happy to look at yours and tell you what I'd do. If you've been thinking about buying one, I can show you which areas and buildings actually reward the upgrades.
