Run a weekly Mashvisor deal scan with your saved filter presets

1. Go to Map Property Finder and type a city or neighborhood in the search box at the top of the page.
2. Click the arrow next to All Properties in the upper-right corner and pick your saved preset; switch the left panel between the Investment, Airbnb Comps and Rental Comps tabs as needed.
3. Click Table to sort the listings by price, cap rate, beds or baths, size or date listed, then open each promising property to read its Property Analytics page.
4. Click Export and choose Export Filtered View when you want the list in Excel; Mashvisor only exports a neighborhood search, so each neighborhood is its own file.
5. Repeat for the next neighborhood. The preset returns every listing that matches, so homes you reviewed last Monday come back alongside the new ones and a fresh listing is easy to scroll past.

Every Monday, run my "Tampa STR under 400k" preset in Ybor City and Seminole Heights, skip anything already in my Saved Homes, and list the 5 best new listings by Airbnb cash on cash return.

1. 01

   Resolve the preset by name

   The agent looks up the preset you named in list_filter_presets. If two presets have similar names ("Tampa STR" and "Tampa STR old"), it asks which one before running anything, because a wrong buy box makes the whole scan useless.

2. 02

   Run it once per neighborhood

   run_filter_preset goes through each neighborhood you listed on the Investment tab. A neighborhood with zero matches is reported as zero, not silently dropped, so you can tell a quiet market from a typo in the location.

3. 03

   Remove what you have already seen

   Before ranking, the agent reads list_saved_homes and drops any listing whose property_id is already there, so a home you saved in March does not come back as a find every Monday. Listings you rejected but never saved can return; tell the agent to save or skip them and the next scan stays short.

4. 04

   Rank by the strategy you buy for

   Listings are sorted by Airbnb or traditional cash on cash return, whichever the prompt names. Mashvisor's figures assume default expenses, so the agent flags results where the return depends on a high occupancy rate rather than presenting them as safe.

5. 05

   Save or export only on request

   save_home adds the picks you approve to Saved Homes. An Excel file via export_neighborhood_data is made only when you ask for it, because each one counts against your plan's monthly exports.

Preset "Tampa STR under 400k", run 12 Oct 2026, Investment tab.
Ybor City: 11 matches, 3 already in Saved Homes, 8 left to rank.
Seminole Heights: 0 matches; check the spelling or widen the preset.
1. 910 E 8th Ave: $389,000, Airbnb cash on cash 10.8%, cap rate 8.1%, listed 4 days ago.
2. 2204 N 15th St: $329,000, Airbnb cash on cash 10.2%, cap rate 7.9%.
Both saved to Saved Homes after your OK. No Excel export used this week.

• Mashvisor saves a preset with Save Filters in Map Property Finder, and deleting one from the preset dropdown happens without a confirmation prompt.
• Mashvisor's neighborhood export does not work on a city-level search, and Export All Data ignores your filters while Export Filtered View keeps them.
• The Mashvisor Lite plan does not include Property Finder, multi-family search or Exporting Neighborhood Data.
• Mashvisor Property Alerts are refreshed with listings updated nightly and email you only when at least one property matches.

save_home changes only your own Mashvisor data and reach no one else, so it runs without asking first.
