Currently house hacking with 2 roommates but I am looking to purchase my first true rental property.Hey Trevor, I personally invest in the Columbus market and have been doing it for the past couple years.

I started investing about 8 years ago personally, then decided to become a professional a few years ago. 

My personal opinion is that a shower door is nicer, but wondering if that's going to create maintenance headaches later. 

I don't personally utilize this strategy, but many other people do so successfully so you might look into that.

House hacking will also give you some personal "property management" experience.

That comes from personal experience as a landlord and working in professional property management lol

Merely my personal opinion, no.

Welcome welcome, I recommend joining up with some local rest estate groups to network with in person and Facebook groups for investors, buy/sell, contractors, etc. to just be in the mix and see who is out there making deals and opportunities.

As that will at least help folks that you reach out to know that you are a real person, with a picture and professional bio.

This question has at least 2 major facets:   1) you personally own the property (or maybe through an LLC)  and 2)  Your 401k owns the property being rented.
