I see several issues here. First buy and hold investors are not created equal.
1) There those that want to hold there real estate to the very end and perhaps transfer to future generations.
2) There those that want to hold for a long period, but do plan to exit at some point.
3) There are those that want to combine these strategies.
Another issue - regards management of buy and hold investments. Some self manage and are quite active in dealing with there investments. Many others have delegated management to property managers.
Exit strategies need to take these all into consideration.
As an investor that actively manages my properties. I know that as I get older, I will transfer more of the management to others. I also will not hold onto every property long term some will get exchanged (1031), some might be sold outright when it makes sense.
The intent is to have a good income stream that insures that my wife and I are will provided for in retirement.
For many buy and hold investors, it becomes necessary to consider estate planning. The last thing you want is to have your beneficiaries lose all or most of what you had to the government, lawyers or possibly infighting.
