These can be cheap/free. My transit is provided by the org that hosts my router + freetransit ( nprofile1qy2hwumn8ghj7un9d3shjtnyd968gmewwp6kyqpqjmapythhk9d874al75x3sftvvgfq9lc926u5zky3ah2dqwuzyeysny9tct (nprofile…9tct) ). In my instance, both are free.
You also need some way of connecting your core router to your home. For this, I tunnel over my domestic retail ISP with wireguard.
