Where we invest we have family so we do visit a few times a year and can always have family go visit the property.

I recommend you go visit a few times to network with local investors or find an investor friendly agent so you can gain local market knowledge, find off market deals and for things such as showings, picture taking or getting accurate comps.

Their different backgrounds will lead to 80-90% of the same stuf being pointed out, but the 10-20% differences can be eye-opening and lead to more accurate bids.Suggest you visit a Home Depot on a Saturday, between 6-8am.

I live in the US full-time and visit a couple times a year. 

We did make a beeline back, cut out visit a day short, though there's very little we can do aside from talk to insurance and talk to the mitigation/restoration company as they work to stabilize the house. 

- If you personally visit a new market, what exactly are you looking for during that visit other than touring some properties?

That is just a one off report so before you spend a buck fiddy, it is a good idea to visit a couple TK operators in person first.

Like @Nicholas L. said, maybe look within a reasonable driving distance from where you live, is there any city or state where you have family or friends that live there where you could travel to frequently and they could keep on the property for you or somewhere you visit a lot.  

Best advice is to join or visit a local REIA meetup and start shaking hands.

Can you give any examples of when you'd need to visit a property?
