Folks have reported light fixtures, sinks, ceiling fans, washers and dryers, refrigerators and stoves, microwaves, etc. walking out the door when the tenant vacates. 

You might find that the existing long term resident isn't a fan of your rules and procedures and might resist change.3) As an agent, I avoid removing the inspection contingency if at all possible.

Previous owner had ceiling light fan combo powered from a receptacle.

Make sure they know to do things like to keep the exhaust fans in the bathroom on for 15 minutes after they shower, use the vent above the stove.

You have a captive audience to reduce that risk. 

I am a huge fan of a house hack so a small multifamily would be my recommendation as they tend to be a little bit easier to house hack when compared to a single family.

Not a big fan or mortgage brokers for investments, I believe the cons are bigger than the pros.Also important: it matters which Loan Officer you speak with at the bank!

I am a fan of doing an LLC for your investment property as it offers a layer of protection (not bullet proof) that insurance doesn't provide but you need insurance either way you go. 

The fan typically doesn't blow hard enough.

Not really a fan of cold-calling (i realize that can be profitable, its just not for me).
