Best and worst cities/areas for multi-family buy-hold landlords

[Ben Feder]

Investors across the nation, where have you found to be the best and worst places to invest as someone who is or interested in being a landlord for multi-family residential properties?

Also, how have you gone about finding out the right information to make this decision, when there is so much information and so many laws out there (landlord-tenant laws, tax laws, eviction, liability, landlord regulations, housing regulations, HOA regulations, construction and additions to buildings regulations, rezoning laws, etc.)?

Any guidance on finding the right professionals (lawyers, accountants, agents, inspectors, appraisers, etc.) to board your "dream team" to accompany you as well?
