To sell a rental investment or remortgage?

[Lalaland44]

DH and I got a buy to let mortgage on our old house 5 years ago and moved into our new house. There’s 13 years left on the buy to let. We make £450 per month profit after fees, Tax and minimum interest only mortgage payments. My question is what’s the best thing to do in 13 years time? How easy is it to remortgage (Dh will be retired by then, I’ll still be working as 7 years age difference!) if we want to carry on renting it? Would it be better to sell it? I’ve read that there’s an 18% Capital Gains for non high earners. The property is worth around £240k buy to let interest only mortgage is £130k. I’m NHS so will have a private pension. DH has an ok pension pot too.

no idea what will happen in 13 years, but if this is England, I'd sell the BTL when your current tenants leave. Section 21 is going to be abolished and the ongoing fallout from covid19 will make it almost impossible to evict problem tenants. Just look on landlordzone to see the kind of arrears that are being built up with no prospect of eviction or payment for at least another year.

you can't get them out (even if you want to) in time for any CGT hike anyway.

Cgt is 28% once your gain is added to your salary though. So once you get above £50,000 of salary plus gain, it’s 28% not a flat rate of 18%...
