My formula is not complex... something like this:High school rating > 8"(Estimated Rent x 12) - HOA - Prop Tax - Insurance @ 0.3% - Vacancy @ 5% of rent - Debt Service @ 8%" > 0I want to be able to customize the metrics, and find properties I can purchase as an investment.If anyone is an avid user of StockRover and their custom metrics, that is exactly what I am looking for - but for real estate. 

Both companies suck but do have impressive customer service outcomes from recent complaints.  

We’re most interested in great customer service, ease of transactions and favorable savings and loan rates for businesses.Thanks!

It helped that I worked as an estimator for a local residential custom home builder for a while.

You can then connect (using Zapier) other online resources with your Google sheets with the newly connected record to run all kind of custom calculations.Hope that helps..

I am an investor myself and have renovated roughly 300 properties for REI Nation, worked for the management company speaking with residents, spent a short time on the customer service side of the business working with existing clients and their portfolios after purchase and to this point have spoken to close to 6,000 interested investors answering questions about Turnkey real estate in general and REI Nation specifically. 

Story: I was waiting until March to list a house for sale - a previous primary home, rural but really nice custom home, great neighborhood full of nice houses, incredible views, etc...So a month ago, in moves a new neighbor, right across the street.

Also don't forget about lead times on custom sizes, older homes can have larger uncommon sized windows.

Average customer use period (must be 7 days or less)3.

Best customer service, better experience, better everything.
