Easier ways I do this are using a site like rentometer.com - which is a subscription service that provides market rents by address with comps OR using zillow and/or craigslist to see what rents are in the area/zip code.

These are professionals with additional training and a stricter code of ethics.

I read 'The Bankers Code' by George Antone and it drew me to private lending.

It gives a total LIVABILITY score for each zip code and neighborhood. https://www.areavibes.com/
