Rent calculators

Rent estimate calculator: what your rental will actually let for.

A rent estimate is what similar homes in the same ZIP code let for today. Dardaris works it out for every US unit on its own, from the Census rents for its ZIP code and bedroom count, blended with leases on Dardaris where there are enough of them. Try it for one address here.

Enter a 5-digit US ZIP code to see what a home like yours lets for there.

Dardaris estimate

Usual range $1,200 to $1,940, from the Census rents for the ZIP code, blended with leases on Dardaris there.

Bringing this to market would add $145 a month, $1,740 a year.

This is the unit page in Dardaris. Every US unit gets its estimate the moment its address and bedrooms are in, with no lookup to run.

The estimate uses US Census rents for the ZIP code and, where at least 10 leases from 3 owners exist, the median rent of leases on Dardaris. No single lease is ever shown.

By hand

Work it out from listings you found

Outside the US, or for a home the Census does not describe well, enter three comparable rents. Once the unit is in Dardaris, you will not need to do this again.

Comparable rents

Homes like yours, nearby, listed or let in the last few months. A third one is optional but sharpens the range.

Size

Square feet or square metres, the same unit for both. Leave blank to skip.

Plus if yours is better (renovated, parking, laundry), minus if worse. A few percent each way is normal.

Checks

For the 1% rule. Optional.

Mortgage, tax, insurance, HOA and upkeep. Optional.

Suggested asking rent

€2.100

Realistic range

€1.950 to €2.250

    How to estimate rent

    Four steps, and the first one does most of the work.

    Every rent estimate, from an agent, a website or this page, is a comparison. The quality of the answer is the quality of the homes you compare against, which is why the steps below spend their time there.

    1. Step 1

      Find three real comparables

      Same area, same type, same bedroom count, listed or let in the last three months. A listing that sat empty for eight weeks is evidence of a ceiling, not a price.

    2. Step 2

      Adjust for size

      Divide each rent by its size to get a rate, then apply the rate to your own size. A home 15% larger does not always let for 15% more, so read the result as a guide.

    3. Step 3

      Adjust for what differs

      A renovated kitchen, parking, in-unit laundry or outdoor space each add a few percent. A busy road, a dated bathroom or no lift take a few away.

    4. Step 4

      Check it against your costs

      The market decides the rent, not your mortgage. But knowing the gap between the two tells you whether the home pays for itself before you list it.

    Zillow rent estimate

    The Zillow Rent Zestimate is a starting point, not an answer.

    Zillow publishes an automated monthly rent for most US homes, built from public records, listings and recent rentals around it. It is quick and it is free. It also cannot see inside your home.

    • What it reads

      Public property records, the listings on its own site and the rents of similar homes nearby. It updates as those change.

    • What it misses

      A new kitchen, a view, a noisy neighbour, a parking space. Anything not in a public record is invisible to it, and those are exactly what move a rent.

    • How to use it

      As one comparable among three. If your comp-based estimate and the Zestimate differ by more than 10%, look at the comparables again before you trust either.

    Two cross-checks

    The 1% rule and your cost floor, and what each one is good for.

    Neither sets the rent. Both tell you when an estimate is worth a second look.

    • The 1% rule

      Monthly rent of about 1% of the property value. It was a buying rule for investors, and in most cities today rents sit well below it. If your estimate is above 1%, check the comparables.

    • The cost floor

      Your mortgage, tax, insurance, association fees and an allowance for repairs, per month. Below it the home costs you money every month it is let.

    • The empty month

      Asking 5% over the market and waiting one extra month costs more than a year of the difference. A fair price that lets quickly usually earns more.

    Rent estimate questions

    How do I estimate rent for my house?

    Find three homes like yours nearby that were listed or let in the last few months, take the middle of their rents, adjust for the difference in size and for features yours has or lacks, then check the result against your monthly costs. That is the method an agent uses, and the calculator above does the arithmetic.

    How accurate is the Zillow rent estimate?

    It is a useful first figure, built from public records and nearby listings, but it cannot see the condition or features of your home. Use it as one comparable among several, not as the price.

    What is the 1% rule for rent?

    A rule of thumb that monthly rent should be about 1% of the property value, so a $300,000 home would let for about $3,000. It was meant to screen purchases, and in most markets today real rents sit below it. It is a ceiling to question, not a price to ask.

    Can I get a rent estimate by zip code?

    A zip code gives you an average across very different homes, which is too wide to price one. Use it to find comparables: search listings in your zip code with the same bedroom count, then enter those rents above.

    Is this rent estimate calculator free?

    Yes. There is no sign-up and nothing is stored or sent: the calculation runs in your browser on the figures you enter.

    What if the estimate is below my costs?

    Then the market rent does not cover the home, and asking more will mostly buy you an empty month. Either reduce the costs, refinance, or accept the gap as the price of holding the property for its value.

    Setting the rent takes an afternoon. Collecting it takes every month after.

    The number you settle on today has to be invoiced, matched to a bank payment, chased when it is late and raised at renewal. That is the part Dardaris does.

    • The rent lives on the leaseOne record holds the rent, its dates and its increases, so every invoice and every answer to a tenant comes from the same figure.
    • Payments matched for youDardaris reads your bank feed and settles each payment against the rent it pays, so a late one is noticed on the day.
    • Renewal with the figures readyWhen the lease comes up, the rent history and the increase letter are already prepared for your approval.
