I don't know if there is a unified theory as to why Detroit ended up where it is now, but I would say it's a combination of (1) over-reliance on a single industry; (2) some epic battles between that single industry and the union; (3) emergence of the automobile industries in countries like Japan; and (4) terrible race relations.  

This creates quite the cushion for emergencies.

I then had them call 211 to have a non profit pay their back rent through emergency covid relief funds.

I like Lindahl's stuff and his book (emerging markets) but it seems that he has ramped up his personal training to a new level which made me a little iffy... a 1$ program email offer recently made me lose my interest.

I just read David Lindahl's Multifamily Millions and his Emerging Markets book too.

Good new mayor, strong emerging areas near downtown.   

You will need both a leasing agent and a maintenance person who can handle emergencies.

Phone is only for emergencies which is generally temperature, fire or water related problems.

I understand you should have an emergency fund to cover for unexpected maintenance or not having tenants and all that but is there some kind of clause on a FHA that allows the home owner to temporarily stay in a secondary home during the reno phase or something of that sort?
