While I am normally in the do-not-sell camp, in this case it might just sell and buy at the new location.

Being a landlord is not an overnight get rich quick scheme.

We live in a microwave world, where everyone expects their investment to soar overnight.

I love how you emphasize starting early and building relationships; it’s a reminder that trust and credibility don’t happen overnight. 

A ring camera will give you the evidence you need to stop a potential party or when people bring in too many guests over night.

To answer the first big question in your post — single family vs multi-family — I am firmly in the multi-family camp.

@Diana Tengput me in the "no" camp or the "no way" camp with @Travis Timmons and @Jay Hurst.and see these threads.https://www.biggerpockets.com/forums/963/topics/1195280-expe...https://www.biggerpockets.com/forums/48/topics/1160450-run-i...https://www.biggerpockets.com/forums/48/topics/1137397-balti...https://www.biggerpockets.com/forums/52/topics/1010977-12-00...before you commit to spending tens or hundreds of thousands of dollars to buy a property, why can't you make a few trips to a market and visit properties in person? 

Generally, both of these situations don't just happen overnight. 

I'm in the camp of change the strategy to increase cash flow, refi, and buy more properties.

I am in your camp and don't check backgrounds.
