Another major US tool brand, this time from Montgomery Ward.

I’d love to know if there is a tool or resource that shows this data.

It's a tool and should be used for the right property in the right area where it makes sense. 

And maybe it's not all or nothing for a given method, sometimes a combination of various financing tools is what wins.

FF is a great tool, but you can also look up local corporate leasing companies, as well as, insurance companies/agents to work with for individuals who are going through home insurance claims.  

Did not know about tools on how screan tenants.

There are rental management tools like Stessa, Baselane, Innago, and many others that include income/expense tracking that handles all the accounting tasks and reporting you really need for rentals. 

You can use Airdna & other STR estimator tools to get data on potential income/vacancy based on your location and property size. 

Even in the off-season - you can optimize visibility by setting competitive pricing, using high-quality photos, and enabling Instant Book with flexible policies.For older listings, try adjusting prices with dynamic tools, highlighting upgrades, and regularly updating your title, photos, or descriptions to stay fresh in search results.These tweaks can make a big difference!

For something more robust, tools like Excel or online calculators from financial planning sites might better suit your needs.Your ROI Formula:ROI = (Net Cash Flow ÷ Total Out-of-Pocket Investment) × 100For your scenario:Net Cash Flow = Annual Rental Income - (Mortgage Payment + 401k Loan Payment + Other Expenses)Total Out-of-Pocket Investment = $40,000 cash + $50,000 loan payments over 5 years.I came across a piece in Bloomberg recently discussing creative financing, and they touched on ROI calculations for multiple loans.Personal anecdote: A buddy of mine leveraged a 401k loan for a fourplex.
