Be where their eyes are searching, but it's not as simple as asking here. 

I tried a big out of state flip due to living in a HCOL area and it failed miserably because I couldn't keep eyes on it and didn't have a good/honest team in place.

Evaluate potential rental properties with a keen eye on location, cash flow, and potential appreciation.

Now, I would not buy a property unless I have eyes on.

Your eyes never stop looking.

I say this because your opening post was like walking up to a buffet and asking the chef if you should have pizza, sushi, ice cream, scallion pancake, spare ribs, or peanut butter and jelly.

It never hurts to have an additional set of eyes to look after your property.

Glad you made your way here.. are you eyeing long-term rentals or short-term flips?

I think the main points would apply to you as well.STR is great, as long as you go into it with eyes wide open and reasonable expectations. 

A "good deal" is in the eye of the beholder.
