Rent or buy a Miami condo
Most rent-versus-buy calculators are built for a house in a market with a $300 a month HOA. In a Miami condo the maintenance fee is often the largest line after the mortgage, and it changes the answer. This one puts it front and centre.
Rent or buy — Miami condo
Estimate only, and highly sensitive to how long you stay and what you assume about growth. Change those two and watch the answer move.
How this is worked out
The tool runs your mortgage month by month for the years you say you will stay, splitting each payment into interest and principal. Interest is money gone; principal is money moved from one pocket to another, so it is counted separately.
Cost of owning = deposit and closing costs, plus every month's interest, HOA, tax and insurance, plus the principal you repaid — minus what you walk away with when you sell. HOA and insurance are grown at 3% a year. Tax is recalculated each year against the growing value.
What you walk away with = the value after growth, minus the mortgage still owed, minus the cost of selling.
Cost of renting = the rent, compounded at the growth rate you set, for the same number of years.
What this deliberately does not do is model what you would earn by investing the deposit instead of spending it. That matters, it is personal to you, and pretending to know your alternative return would be false precision. If you have a real alternative use for the cash, weigh it against the difference this shows.
The number that actually decides it
Not the interest rate. Not the price. How long you stay.
Buying carries a large cost at each end — closing costs going in, brokerage fee and stamps coming out. Spread over two years, those costs are brutal. Spread over ten, they are a rounding error. Every honest version of this calculation has a break-even point, and for a Miami condo with a meaningful HOA it usually sits somewhere between four and seven years, depending on the fee.
Set the "how long you will stay" field to two years and then to ten, and you will see the answer flip. If you genuinely do not know, that uncertainty is itself the finding: renting keeps the option open, and options have value.
What renting in Edgewater actually involves
One thing that surprises people moving from other cities: in most Miami condo buildings you do not simply sign a lease. The association has to approve the tenant, which means an application, a fee, sometimes an interview, and a wait of two to four weeks. Many buildings also set a minimum lease term — commonly six months or a year — and cap how often a unit can be re-let.
None of that is a reason not to rent. It is a reason to start earlier than you think you need to. The Edgewater rental guide sets out the approval rules building by building.
And if you buy
The carrying cost is the thing to get right before anything else. Thecarrying cost calculator breaks the monthly figure into its parts, and the condo law guidecovers what to read before you commit — the reserve study, the minutes, the budget.
Questions people actually ask
Why does this show renting winning when other calculators show buying?
Usually because other calculators either omit the HOA fee or assume aggressive appreciation. Put a $1,100 monthly maintenance fee into any honest model and the break-even point moves out by years. That is not an argument against buying — it is an argument for buying with your eyes open.
Does it account for the tax deduction on mortgage interest?
No. Whether it helps you depends on whether you itemise, your bracket, the SALT cap and your own circumstances — and for many buyers it is worth far less than they expect. Ask your tax adviser and treat any benefit as upside on top of what this shows.
What if I am buying in cash?
Set the deposit to 100%. The mortgage disappears and what remains is the HOA, tax, insurance and the cost of selling, weighed against rent.
Is 7% a fair cost of selling?
It is a reasonable placeholder covering the brokerage fee, documentary stamps and closing costs. Brokerage fees are negotiable and are not set by law. Change the figure to whatever you actually agree.
