Hi Joe,
If the Barn and Carriage house are a true asset I'm sure you can put them to use with the different plans you mentioned. If they need a lot of work to get in shape or just maintain, then selling them could be an option. We restore vintage architecture, particularly barns and ag-industrial buildings.
Do you know when you structures were built, are they a sawn frame or hand hewn?
You may be able, if the type is correct, to
sell one for the money to repair the other.
Sponsoring a restoration workshop is another possibility.
Good Luck, and give a "call out,"
should you have more questions.
Regards,
jay
