How to inspect house when purchasing out of state

[David Yee]

Hello! I am currently reading J. Scott's The Book on Estimating Rehab Costs. I plan to purchase my first property within the next year but will most likely be doing so out of state due to financial constraints. 

How can I go about inspecting a home while out of state? Do I need to fly there? Doing so doesn't seem very cost effective. Thank you!
