Older properties (100+ years) can definitely be solid investments if the numbers work, but there are a few key things to keep in mind:Systems & infrastructure — plumbing, electrical, and foundations often need major updates.Insurance — some carriers charge higher premiums or have stricter requirements for older homes.Maintenance costs — factor in higher reserves for ongoing upkeep.Historic value — in certain markets, these homes can actually attract strong demand because of their charm and uniqueness.If you have a solid inspection team and budget for the extra unknowns, they can be great opportunities.

Our carrier said they had to make up for large claims across the board.  

Already seeing airplane routes going through TYS with added carriers and routes--largest growth in the country last year, so that tells me we'll continue to see some development.

I don't know who your carrier is or what their policies are but I can give you some general information.  1.

Standard preferred risk carriers typically won’t insure short- or mid-term rental properties, but we do have a couple of solid markets that can cover you properly. 

@Juan David MaldonadoYou definitely need to let your carrier know if you alter the currently insured use of the property. 

A true “no coinsurance” policy for a 6-unit is very hard to find because carriers almost always require it. 

One more consideration: the type of trust you utilize may limit your insurance options as carriers like to know who it is that they are insuring.

If you're buying at auction, then yes, it's hard to turn the aircraft carrier that fast, but also as a lender, I often find that borrowers wait until the last minute to discuss deals with us.

Meaning that rates don't change because of the name difference, but some carriers may not write an LLC so you have limited options to choose from.
