Mashvisor automation · runs weekly

Compare all your Mashvisor Saved Homes side by side

Saved Homes is where every deal you liked ends up, and after a few weeks of searching it holds a dozen or more properties. Before an offer you need them in one ranked list, with both rental strategies, and Mashvisor shows them one Property Analytics page at a time.

Cotlet does it in your own Mashvisor account with list_saved_homes, get_property_analysis, get_property_comps and download_property_report, called by your AI agent, an n8n workflow or a script.

Can Mashvisor do this on its own?

Mashvisor offers Compare Properties Side By Side for up to four properties on its Standard and Professional plans, not on Lite (checked 12 Oct 2026). There is no export of Saved Homes with their analytics. The Data API can analyze a property you name, but it cannot read your Saved Homes and is a separate plan from $129 a month.

By hand

How you do it in Mashvisor today

  1. Click the heart icon in the top-right corner to open Saved Homes, which lists each property's type, sale price, your rating and tenant occupancy status.
  2. Open a property to reach its Property Analytics page and read cash flow, cap rate and cash on cash return on the Rental Strategy tab, switching between short-term and long-term.
  3. Copy the numbers into a spreadsheet, then go back to Saved Homes and open the next property.
  4. On the Comps tab, check the Short-Term and Long-Term comparable listings for the homes that still look good.
  5. Mashvisor's side-by-side compare takes up to four properties, so a longer Saved Homes list ends up compared by hand, and figures copied last month go stale as the data updates.

How to compare all your Mashvisor Saved Homes side by side

Prompt

Compare every property in my Saved Homes: price, Airbnb and long-term cash flow, cap rate and cash on cash return, ranked, with the three nearest Airbnb comps for the top two.
  1. 01

    Take the whole list, not the first page

    The agent reads list_saved_homes up to its limit and keeps your rating with each property. Homes you rated low are still compared, but marked, so a 1-star home that suddenly ranks first gets a second look instead of an automatic pick.

  2. 02

    Pull both strategies per home

    get_property_analysis runs with strategy both, so Airbnb and long-term figures come from the same moment. A home that comes back without an Airbnb estimate is ranked on long-term figures only, and the report says so instead of treating the missing number as zero.

  3. 03

    Rank on one metric, show the rest

    The ranking uses the metric you name; without one, the agent uses cash on cash return and says so. Cap rate stays in the table because it ignores financing, which tells you which homes only work with a loan.

  4. 04

    Check the leaders against comps

    For the top homes only, get_property_comps adds the nearest short-term comps. When the estimate is well above what nearby listings earn, the agent says the ranking rests on an optimistic number.

  5. 05

    Reports on request

    A PDF from download_property_report is made only for homes you name, because every report uses one of your plan's downloads. Nothing is removed from Saved Homes in this job.

What you get back

Before you automate it

What Mashvisor allows, and what to know first

  • Mashvisor's Compare Properties Side By Side is limited to four properties and is missing from the Lite plan.
  • Mashvisor fills in nationwide default expenses: $83 a month insurance, $100 a month utilities, 6% property management, maintenance at 1% of the price and 14% rental income tax.
  • Mashvisor counts only the down payment and startup costs as invested cash for cash on cash return, while its cap rate ignores financing, so the two are equal for a cash purchase.
  • Each Mashvisor PDF report shows the downloads you have left before it is created, and a branding logo can be at most 100 x 100 pixels and 1 MB.

Every tool here only reads, so it can run weekly from n8n, Make, Zapier or cron without waiting for your OK.

Frequently asked questions

Does it use the expenses I edited in Mashvisor?

get_property_analysis returns the figures Mashvisor shows on the Property Analytics page. Mashvisor starts from nationwide default expenses and says to adjust them for your area, so the agent states when a comparison runs on defaults.
