I personally would think you have plenty of deals within your local area to retire off of. I have a few out of state properties due to moves for my job. When one becomes vacant, and they are unmanaged, it is somewhat stressful as a beginner; however, it still can be profitible. I would not voluntarily buy one out of state. Now you have another state’s law to learn as far as eviction and such. If you got ready to sell it, you’d just about have to go with a realtor due to the difficulty showing the property and tracking all the correct phone numbers down for appropriate advertising.
If you do decide to go for it anyway, i’d try to get decent terms with the owner financing it rather than going thru the nightmare assumption process. With rates as low as they are today, you might be able to do better with your own loan.
Hope this helps a little!
