Buying land, titles, property in 5E.

Ok, this is way off in my 5E campaign. But I'm sort of looking at setting the groundwork for the possibility the characters possibly buying titles, land, property etc.



So on the lines of buying off those sorts of things from a local lord.

Perhaps some lands that are overgrown now and wild. It may have had an old building that needs refurbishing and garrisoning.

Maybe even do a mini hexcrawl type campaign to clear a certain amount of hexes for the lands they buy the rights to.



Does anyone know if the DMG will handle this sort of thing?

If not, does anyone have any very 5E compatible rules for this?

I think there were some sourcebooks available for DnD for stuff like castles, but I don't know if they covered:



buying land

Buying Titles

Buying property

Maintaining castles/property

Hiring staff, soldiery etc.



I don't want to turn it into a huge resource management game either, so this sort of thing at a high level, rather than up close and detailed is preferable.



My idea is when they eventually finish "The temple of elemental evil" they might want to take over the moathouse and clear the area of bandits and monsters etc and refurbish the Moathouse for themselves.

Sort of semi retire the characters and start over.
