If my goal is turnkey/buy and hold properties, should CoC really matter?

These are some options that I am considering. 1) Getting an LLC and a Joint Venture agreement to partner with a long time friend of mine but somehow separate our business from our individual marriages?

This is definitely a place where you can learn and move toward that best version of yourself.

I could refi and have the property for free plus maybe 5k and $120/mo but to me - that just isn't a good return. 

Hey @Juan Carlos Correa and Welcome to BP!

I went into the bedrooms and don't notice the sloping floors so much just by 'feel' and admittedly haven't put any measuring device like a level to it. 

They just seem to have the people and resources to best handle big issues like that. 

Once before the lease signing and often at the lease signing.

I'm planning to invest, start small and get my way up which area you think is the best for me to start looking?

Most serious and qualified tenants are searching on the major 3rd party platforms you mentioned + realtor.com, redfin, and a few others.Apartments.com & homes.com are owned by the same company and may offer some additional marketing options.Another strategy to consider here is social media - video marketing.
