I found that the nuisance/worry factor in being a long-distance landlord of my former home outweighed the long-term benefits and sold up (and then bought a rental locally, mostly for non-financial reasons) after a few years. The problems of a long-distance rental can be offset by knowing a reliable cadre of local workmen to carry out repairs and maintenance and having someone local to find and vet tenants. Having family in the area is an advantage if they can provide any of those services (don't take them for granted, pay them) and also if they can provide you with a place to stay if you have to visit the area to deal with any house issues.
Of course, keeping the house as a rental may also affect what you do for housing in your new location: whether you can buy down there and what you can afford if you do. So that needs to be factored into any decision.
Long term you are going to be all right financially whatever decision you make: real estate and index investing are both good ways to reach financial security and independence. So I think you should do whatever feels right to you and that you think you will regret the least: it's very unlikely to be much of a mistake whichever way you jump.
I'm pretty hands on and proactive even when maintenance items and such do arrive. I guess my financial situation isn't bad now
and would only be improved by going to a better job so I kind of figure why not try out a rental on something I have good equity in/have family and friends in the area?
current financial situation:
60k liquid
30k roth
no debt
115k mortgage 4.25 30 year. House let's say 190.
It it would sell for $190k, you want it to be able to earn $1900/mo in rent. If not, you are likely better off financially selling it. And that's not considering the emotional and logistical concerns.
Also, being a long-distance landlord can be challenging. I can't imagine doing it without a property manager, but they take a good chunk (usually close to 10%) of the rent.
I do think it's time to start gently bringing up a timeline for moving. Consciously or not, slow-rolling that process is a way for her to keep one foot in the door of this relationship. And it prevents both of you from moving on.
"I know this is painful and uncomfortable, but I think it's time we talk about a plan for getting your stuff moved out of the house. I need to start getting it cleaned up and ready to sell or list as a rental. Do you think it's realistic that you have your stuff out by the end of the second (or third, if you must) weekend in August, so August 11? [or 18] Also, I plan on being out of the house all day on Saturday [even if you have to manufacture a reason and a place to go] so that would be a good time for you to come by. If it works better for you, I can move my plans to Sunday. Let me know if that works for you, and if not, we can see if there's a compromise.
I know this is hard, and awkward, but it's the only path forward I can see. [NOTE--I would probably leave this off, but it's clear you really prioritize being super gentle. This does slightly soften things so it is a bit less cold and business like--which is why I'd leave it off--but if you have to say something, at least this doesn't delve too far into emotions and things she can try to argue and rationalize, or things she can spin to create hope.]
And, as others have said, you are doing great. This shit is hard. It is. I once broke up with a boyfriend (and it took me longer to do than the length of this thread, even after I'd 100% made up my mind!) and when I'd finally done it, a couple days later, he wanted to go to Disneyland. We had passes, and it was a thing we did together a lot, and I thought it would be kind to show him we were still friends. We went, and somehow, we ended up back together. I don't know if it was an intentional misunderstanding/manipulation on his part. But I was afraid to be assertive because it felt "mean". When he grabbed my hand, I knew it would hurt him if I pulled away, so I didn't. And one thing lead to another and suddenly everything was exactly as it had been and I knew he thought we were back together. So then I had to break up with him a second time. It was terrible, and it was all because I couldn't bring myself to be mean to this person I cared about, and I equated "firm" with "mean". When really, what I ended up doing was far more hurtful and mean.
Then, I initially left the moving out part ambiguous because it felt like kicking him when he was down to say, "have your shit out by Sunday." (He ended up moving in with my at my parents' house 'temporarily' when the room he was rented was no longer available. In retrospect, I think he absolutely did this because he knew things were dying and it made it harder for use to end things.) So I just left it as "I'm in no hurry, take the time you need to make arrangements," and that meant those arrangements never came. he'd come by, grab a few things, ask to talk to me, tell me how sad he was and how destroyed was his world, etc., then leave with three pairs of socks and a off-season piece of clothing. And repeat, and repeat, and repeat. Finally, I had to tell him, "look, this isn't good for either of us. I need you to be moved out in two weeks." That was awful. But it would have been better if I just had that one "awful" instead of the weeks of baby "awfuls" leading up to it, plus ultimately the same hard conversation.
He kept trying to engage. I had to resist the urge to coddle him. When he sent long, emotional emails, I either didn't respond, or only responded to the logistics parts and ignored the emotional stuff.
This stuff is so hard. It truly is. I don't think anyone here believes otherwise. But you will make it through this, and there's a way to do that which minimizes the additional, lingering hurt for both of you and allows you to sooner start the healing part.
