Dave Ramsey is to Real Estate Investing what Subway was for Dieting. 

I found an app for finding subway/bus routes.

My ideal would be a 2bedroom condo in downtown or on a subway line. 

@Ben PatelI presume you’re a franchisee of Subway.

- Consider a bold color or pattern for a statement look.Inspiration: - Explore subway tiles for a classic yet stylish appearance

We did the following things1) Incentivize the behaviors you want: I didn't charge late fees if tenants notified me and stuck with an acceptable payment plan. 2) Be fair-- don't charge tenants when old crufty end of useful life fixtures or finishes have to be replaced. 3) Appreciate it and fix things when tenants properly report problems. 4) Renovate as required to get the kitchens and baths actually clean, clean. 5) Make your apartments look better than others (and show that you care about your properties) by adding at least a couple of special touches like modern lighting, invisible cabinet hinges and/or cabinet paint and a subway tile backsplash (Lowes sells 3x6 white tile for .15 / tile) and a restaurant style sprayer faucet.

Currently I'm adjusting our search criteria based off the feedback I'm getting from tenants like Mcdonalds, FIve Guys, Auto Zone, CVS, Sonic, Subway, ect...The first property we got under contract was directly on a highway with with a vehicle per day count (13,000), but had a 1 mile population density of under 1,000 making it too rural for many of the tenants we talked to. 

Buying near an L station is a good idea, but know your subway lines!

Subway was a company in mind, they have a real estate page and a user friendly process which I intend to submit out of desperation.I would rather do it myself, and not with a broker.

It can be their secret subway system between the units or between the buildings, or from the main system buried in the road to the building.
