LandLord allows you to become the landlord of various properties around Skyrim. And like a landlord in the real world you'll make money off your tenants provided you know what you're doing.
This mod allows you to purchase the game's shops and taverns. To do so, you simply need to walk in and talk to the owner about his or her business. Oh, and you'll also need a lot of gold so make sure you don't walk in empty-handed.
The price of the establishment will depend on a few factors including your race, your speech skill and your relationship with the owner. You'll also notice that the pricier places produce the most income.
Once you go into business you'll get a discount at the store and you'll also get a weekly income that can be boosted with a trade route which in turn opens up access to Markarth's Treasury House where you can use a chest to boost your weekly income.
This is a good one and it's worth a download today. For more, take a look at the video below.
