The key is to find one that builds the type of houses you want to build, get several current and past client references and call them, visit a couple of finished projects as ell job sites in progress as you can tell a lot about a builder by the way they keep a job site.

That could be the extent of my work or, it is possible, that in the future I may be called upon to actually visit a property as well. 

I doubt my team would want to visit a number of properties daily.  

If market rents are $200-300 higher than what your target property is receiving, then you just need to examine what amenities and features these other rentals have that yours doesn't.Go visit a few neighborhood properties that currently command a higher rent and make careful note of the interior and exterior.

I target off-market out of state places, but in areas where I have a person to check out the places and kinda be the seller's go-to person Or in areas I visit a lot. 

There are so many investors from your area right here on BP and there are so many local meet-ups that you could probably visit a different one every night for a month.  

You may want to visit a few mobile home parks and mobile home dealerships.

I think we'll plan on traveling to visit a couple of the cities we're interested in. 

If possible, go visit a few of the best ones to see how yours compares because pictures can be misleading.You should regularly watch your market, not just when you have a turnover.

Go out and visit a few mobile home parks to see which ones you like and which ones you don't like.
