London vs Miami: Two Opposite Cost Philosophies
Featured Question
Is London or Miami better for property investment?
Miami offers far lower purchase costs (2-5% vs up to 10-15% for non-residents in London), no state income tax and stronger price momentum — but insurance averaging $12,200/year in Miami-Dade, 1.8-2.2% uncapped property taxes and escalating HOA fees make annual carrying costs the decisive risk. London is expensive to enter but cheap and predictable to hold. The choice is entry cost versus holding cost.
Miami has surged onto international buyers' radars: sunshine, dollar assets, no state income tax. London remains the classic safe haven. The entire comparison compresses into one sentence: London is expensive at the moment of purchase; Miami is expensive for every year you own. This guide runs the 2026 numbers on both.
Quick Answer: Miami closing costs run 2-5% (as low as 1-1.5% for cash resales) versus up to 10-15% for a non-resident buying in London, and Florida levies no state income tax. But Miami-Dade insurance now averages $12,200/year on a $300K dwelling, property tax runs 1.8-2.2% with no cap for non-homesteaded (foreign) owners, and HOA fees plus special assessments can push carrying costs to 3-4% of property value annually. London's holding costs are low and predictable; its entry tax is heavy. Short horizons favour Miami; long horizons change the math.

Purchase Costs: Miami Wins Decisively
The direct answer: buying is far cheaper in Miami. Cash resale closings can run 1-1.5%; financed and foreign-buyer scenarios typically land at 2-5%. Florida has no mansion tax. A non-resident buying in London can face total acquisition costs of 10-15% of price once SDLT surcharges stack.
- Cost: Purchase tax/closing · London: SDLT 5-12% + 2% non-resident + 5% additional → up to 10-15% all-in · Miami: 2-5% (cash resale 1-1.5%)
- Cost: Annual property tax · London: None on owner (council tax paid by tenant when let) · Miami: 1.8-2.2%, uncapped for foreign owners
- Cost: Annual insurance · London: Building policy inside service charge; moderate · Miami: Miami-Dade avg $12,200/yr ($300K dwelling); roughly doubled in 5 years
- Cost: Monthly fees · London: Service charge (high in concierge buildings) · Miami: HOA $300-1,500+; luxury $2,000+; special assessments can reach five-six figures
- Cost: Withholding on sale · London: None · Miami: FIRPTA: 15% of sale price
Holding Costs: Miami's Invisible Invoice
The direct answer: Miami's real risk is not the price — it is the cost of continuing to own. Three line items now compress the 2026 condo market — HOA + insurance + property tax — and on sub-$1M condos they frequently equal or exceed the mortgage payment. A concrete example: a Brickell condo carrying $1,400/month HOA, $900/month property tax and $200/month insurance bleeds $2,500/month — $30,000 a year — even if it sits empty.
The second structural risk: post-Surfside inspection laws. Buildings that deferred maintenance are issuing five- and six-figure special assessments, sometimes overnight. A beautiful unit in a financially troubled building is a terrible investment — honest Miami brokers say this themselves. Always request the reserve study, milestone inspection report and assessment history before offering.
Third difference for foreigners: Florida's 3% annual assessment cap (Save Our Homes) applies only to homesteaded residents. A foreign investor's property tax rises uncapped.
Optivest Note: We have written harshly about London's service-charge problem, and fairness requires saying this: Miami's HOA-plus-insurance problem is currently the heavier of the two. But remember that London concierge buildings can still absorb 20-40% of gross rent in charges. The rule is identical in both cities: underwrite the building's finances, not just the flat.
Market Momentum: The Honest Score Favours Miami
London loses this section, and we say so plainly. Miami-Dade sales have risen for nine consecutive months as of May 2026; the single-family median is $685,000 (+4.2%), the condo median $425,000 (+2.8%), luxury sales are up 14.7% and inventory down 11.9%. International buyers made up ~18% of Q1 2026 closings, averaging $850,000. London prices, by contrast, have fallen in real terms in recent years, with 2026 forecasts at 0-2%.
But there is a crack inside the momentum: the $300,000-600,000 mid-market condo segment is under pressure precisely because of the HOA and insurance shock. In Miami, building selection matters even more than in London — momentum will not rescue the wrong building type.
Tax and Law: A Complexity Gap
- Miami: No state income tax — a genuine advantage. But federal rental-income filing, ITIN applications, FIRPTA 15% withholding on sale, and treaty interaction with your home country all apply. US estate tax for non-resident foreigners starts above a $60,000 exemption — a serious planning issue on high-value property that sales brochures rarely mention.
- London: SDLT is heavy, but what follows is clean: NRL Scheme on rent, CGT with 60-day reporting on sale, and a 160-year public title register with independent courts for disputes.
In both countries the rule is the same: do not buy without an internationally experienced tax adviser. Optivest does not provide tax advice; we signpost qualified UK tax advisers and, for the US, internationally experienced CPAs.
Climate Risk: The Conversation That Must Happen
Miami's insurance crisis is not random: hurricane exposure and sea level are being priced in, which is why premiums have roughly doubled in five years. To be fair, HB 913 (2025) eased reserve-funding rules and some carriers have returned to Florida — partial stabilisation is real. London's climate-linked insurability risk (outside mapped flood zones) is not comparable today. Over a 10+ year horizon, this gap compounds.
Who Should Choose Which?
- Profile: Dollar asset + lifestyle use (winter home) · Better fit: Miami · Why: Use value plus momentum
- Profile: Remote, low-touch, predictable investment · Better fit: London · Why: Holding-cost stability
- Profile: Short horizon (3-5 years) · Better fit: Miami (right building) · Why: Cheap entry + momentum; price FIRPTA in
- Profile: 10+ year capital preservation · Better fit: London · Why: Miami's climate/insurance risk compounds
- Profile: Cash-flow priority · Better fit: Neither is strong · Why: Miami's carrying costs and London's entry tax both erode net
- Profile: Estate planning priority · Better fit: London (with care) · Why: US estate tax $60K exemption is punitive for foreigners

Frequently Asked Questions
What is the biggest hidden cost for foreign buyers in Miami?
Carrying costs: 1.8-2.2% property tax (uncapped for foreigners), insurance averaging $12,200/year in Miami-Dade, and HOA fees of $300-1,500+ monthly. Together these often exceed the mortgage payment on sub-$1M condos. FIRPTA then withholds 15% of the price at sale.
What is FIRPTA?
A US federal rule requiring 15% of the gross sale price to be withheld when a foreign person sells US real estate, as security against tax due. Final liability is settled by filing, but the withholding locks up cash at completion.
Where is London weakest against Miami?
Entry tax and momentum. Non-resident all-in costs can reach 10-15% versus Miami's 2-5%, and Miami prices are rising in 2026 while London is broadly flat.
Why is the Miami condo market split in two?
Luxury is strong (+14.7%); the $300K-600K mid-market is squeezed by the HOA and insurance shock, and post-Surfside inspection laws have triggered large special assessments in older buildings. In Miami, the building is the investment.
Which market is easier to exit?
London's resale market is deeper and fully transparent. Miami liquidity varies by segment — and an empty Miami condo can cost $2,500/month to hold, eroding net proceeds fast if a sale drags.
Conclusion
The London-Miami decision is entry cost versus holding cost: Miami is cheap to enter and expensive to keep; London is expensive to enter and predictable to keep.
