Generally, I would steer clear of rental properties that have too much vintage functional features. 

This is a direct result of the robust job growth in North Texas.

A good example of scaling this beyond the original function can be seen with Chris Clothier and his company that recently regraded from Memphis Invest to REI Nation.  

And every Ma and Pa investor wants these because they are easy to manage and easy to rent, even though they don't cash flow spectacularly like my "little ATMs", 2-bed, 1 bath bungalows with dated but functional amenities.To generate leads, my favorite strategy is keeping 3-4 agents on the line who know my criteria. 

I have just implemented a bot function on my FB business page to automatically pre-screen tenants and direct them to my Cozy page to apply.

I used this other rental property calculator called DealCheck that has the same functions as BP, but I was able to customize my loan amount and decide whether I want to include the rehab costs or not.

@Paul Welden if you can DM me (not sure if that functionality exists) I’d love to know some lenders that specialize in 203k loans across the country

This type of entity was designed to function at a much smaller level of a corporate entity. 

But all of that has created such a robust mental image for me of what needs to be done on a property.

An analysis should be done for multiple different possibilities / situations to make sure the deal is as robust as possible.
