Description

How it works
Uses the rentcast.io api to get approximate value of real estate. Updates the asset in YNAB.

Setup

Get Rentcast.io api key
Get YNAB API Key
Get YNAB Buget ID and Account ID

This can be done by navigating to your budget in the browser, then extracting ID from the URL

https://app.ynab.com/XXXX/accounts/YYYY
xxxx = Budget ID
yyyy = Account ID

If you don't already have an account to track your property, create a new Unbudgeted tracking asset.




Set the veriables in the 'Set Fields' node (Or setup subworkflow if you have multiple properties).
