I'm currently investing in Jersey City area and understand the zoning laws recently changed.

My company has done 1031s for 31 years, we work in all 50 states, and we're very good at what we do. 

Louis and the surrounding cities that I should start looking into?

I might wait until the picture becomes clearer regarding the city's newly liberalized building code which will apparently allow the use of CPVC and/or PEX water supply piping.

I do have sample of two cities, Indiana city with zero appreciation and meet 3x rules and/or Wisconsin property that has CF as well as appreciation.

Chicago is a great city to get started with House Hacking.

Rent demand notices must now have two service attempts on two separate days before it can be posted on the propertyRather than utilizing technology and streaming the legal rental demand process as some states are doing; in Colorado, rental demand notices need to be physically created, printed (in the tenants preferred language), and physically delivered to the property.

It looks a lot cleaner than the one I saw at my state park.

I will be focusing on the Baltimore City tax sale, but I imagine there might be much overlap in our areas of interest.On another thread, a fellow BP member (@Matt Schelberg) suggested that I get in touch with a Maryland tax sale attorney, which was really useful advice.

As an out of state investor, he's been very helpful to me.
