Its a bad idea to settle in it , better to settle outside that town even if its just nearby.
1) You can't open the doors bcos is has a lock on it & the previous owner holds the keys.
2) Since u are only 5 days , i assume you can't even scratch the stone wall let alone destroy the wall . in other word, if someone were to repair the hole in the wall, you will be locked in.
I would suggest build outside the town , if u really want to build inside , wait till u can destroy the gate , then build ur own gate & lock/key.
best to find a place when u can see forest, grassland & a river/lake for the materials you will need , of course u can roll alts to gather materials that u need from other part of the maps. For water , u can always carry a few buckets & port to boston to get it.
Note : Best to build ur home next to a mine as you can store movable items inside the mine , this save up space above the surface = save silver on space upkeep

. Use Woo Woo Wand to find the minepoint & settle beside it but remember not to build anything on top or 1 tile from the minepoint so u can build a mine in the future. Woo woo wand can find a lot more mines than Rods but the down side is you will not know what purity the ore mines is until u build one to get the ore but since u just need it for storage space & normal iron bars for nails , its ok. As for lime , hope there is a lime quarry nearby or u can roll an alt char to settle near a lime quarry or u can smelt iron without using lime.
I just found 8 minepoints near my home last nite with a woo woo , & 3 of them is only 20 tiles distance from each other.
