"My mother and I have an arrangement, siblings are not included, but they seem to think they have a say in who and how the home is used on my property." At its core, that's what this guy's story is about

Because family real estate plans always go smoothly until somebody imagines a free vacation home that does not exist. In this case, the vacation home does exist, just not in the way the siblings seem to think it does

  • The couple built a mountain cabin, then poured effort and cash into an attached guest unit for the mom, covering its upkeep, taxes, insurance, and basically turning it into a paid early inheritance. The understanding on the ground is simple. Mom lives there. Family can visit when she is there. No grandma, no siblings, no kid chaos in the yard. That line has been drawn out loud and repeated more than once.

  • Two years ago my elderly mother mentioned she'd like to have a cabin near me and we talked about buying one near us.

  • After viewing several homes, and realizing how expensive it would be to purchase, we decided to consider an ADU (attached dwelling unit) on our large lot.

  • The deal was that my wife and I would allow it to built on our property, and we'd cover maintenace, all utilities, taxes and insurance, etc.

  • The rest of the siblings mostly treat the whole setup like a long-term Airbnb listing. Never visit. Do not show up when invited. Carry on with their own lives. Then, when they find out about the new cabin, suddenly they are extremely invested in vacation planning and “inexpensive getaways.” The math in their heads is easy. Same mountain, same family, therefore free lodging. The math in reality is that the cabin is on someone else’s lot, with its own rules, and its own owners who are not in the family rental business.

  • Ultimately it was an early inheritance transfer. Here is the rub and where I would appreciate feedback, and to help understand if AITAH.

  • I have a couple siblings, they've never visited, and weren't not close. They often rent homes in our area, but still never visit, even when we offered.

  • When they found out my mom was considering buying, they were excited, because in my opinion, they were getting access to a free vacation home, but ultimately were left disappointed when my mother decided to build on our property.

  • The worst one of the siblings is now messaging the mom, pitching little family trips, sliding a boyfriend and a kid into the equation like they are just asking to borrow a lawn chair. The pattern is clear. Rules are for other people until they are not convenient. Once told the cabin is not a public family resort, the response is to keep nudging anyway, hoping persistence equals permission.

  • Recently I found out my least favorite sibling (and new boyfriend, and kid) has messaged my mom and stated, "they'd like to plan some inexpensive vacations and would like to use her new cabin." I have a problem with this because "her" cabin is on my property, and we share an extensive common use area and I don't want to start a trend of random family members thinking they can freely use grandmas cabin at their leisure.

  • The rules my mother and I established in the beginning was that family could visit IF they were visiting when she was present.

  • Essentially, if no grandma, no siblings, no nephews/nieces, etc. This has been communicated to everyone. My mother and I have discussed this and have aligned on general use rules when it comes to family use, but this one sibling continues to push.

  • My mother has now directed her to me, I'm planning to draw a hardline in the sand.

  • Drawing a hard line is not being harsh. It is protecting an agreement that is already in place, an arrangement between a couple and the mom, not a crowdsourced housing project. They are not shutting anyone out of the relationship. They are not banning family dinners. They are refusing to turn a carefully set boundary into a revolving door because some relatives cannot read the memo.

  • So AITAH? In my opinion, my mother and I have an arrangement, siblings. are not included, but they seam to think they have a say in who and how the home is used on my property.

  • glasshopper85 NTA. Your home is your peace and peace doesn't usually involve mooching siblings. You two have an agreement and I'd stick to my guns.

  • Fit-Discussion-4910 NTA. This is less about the cabin and more about entitlement. They showed no interest in visiting family until there was something to gain. The agreement was already defined and fair. Letting one person bend it opens the door for everyone else and then you lose control of your own property. Drawing a firm line now actually prevents bigger conflicts later.

  • 11Turnips I think I see why she's your least favorite sibling. Nta. You and your mom agree. Mom is just tired of putting up with her and wants you to maintain that hard line in the sand. Do you have a good lock for it? So you don't find sis and crew have just shown up anyway? Sis needs to learn No means No.

  • logical-sanity NTA. Draw that line in the sand and make sure mom doesn't give any of them a key to the new abode.

  • Spinnerofyarn NTA. "Part of the agreement with Mom in allowing her to build on our property was that no guests are allowed if she's not there. We notified the whole family of this, and you were included. We know you have asked Mom and she has told you no. Now you're asking us to override that policy. The answer is no, just as it will always be no. I'm really bothered by how disrespectful you're being to her by not accepting her answer that we required as part of allowing her to have a cabin on o
