Mortgage term in early 50s (solo): does £98k still feel manageable?

[51With98kLeft]

As per new username: is anyone in their early 50s, with 98k left on their mortgage (which they pay on their own)? How long is your remaining term? Does it feel manageable? There are obviously lots of variables to this, but in general?

Current mortgage almost paid off (tiny monthly payments now) and have opportunity to buy DSib's part of inherited property (one part left to me). I'd buy it for disabled DC to live in eventually. DP thinks it is too much of a commitment because of my age and that I would have to take the term right up to my retirement from a public sector role.

I wouldn't need his support (but I resent that he wants to pass up the opportunity to secure a future home for our DC because he thinks it's all just a bit too much to take on).

Just wanting a reality check.

I took on a mortgage of a similar size when I was about 46 - it's manageable and doesn't scare me too much! I work in teaching so it's a pretty secure career I guess.

I did it because it was the only way I could have my own place (renting feels so insecure now) - so it didn't feel like much of a choice in a way. Whether I would have done it in your circumstances I am less sure, but I think so!

I think the fact you already own 50% of the house really lowers the risk factor mentioned by PP’s x

I didn't notice that new responses had appeared over the weekend, thank you.
I've crunched the numbers inside out and back to front, and could technically manage it on my own without letting it, while still honouring my financial commitments in the home I share with DP.

@StrictlyCoffee I considered just selling up with my sibling and saving my share for DC, but then, at the time when DC would be old enough to want to move out, they'll probably not be earning enough to get a mortgage irrespective of how big the deposit is (DC1 will not earn a salary as such ever due to disability). So even with a large deposit, the way I anticipate house prices will rise in the next decade, they'll just have a deposit with no means of securing a mortgage, and I'll be too old to take out a mortgage on their behalf by then.

I have considered making it my official residence (it's nearby) and having a lodger rather than a tenant, while still spending my time in our family home, as the rental income I'd need to raise to pay the monthly mortgage repayment is closer to what it costs to rent a room in our city per month -I don't need the kind of rental income which comes with letting a whole house, if that lets me off the headache of being a landlord. But I'd be able to pop in to the property everyday without any extra hassle, no further than popping to the shops on foot.

I should have added to the previous post; the proximity is a big factor in why it would be so convenient for DC1 to live there eventually -it would be very close.
