Sell up now while long term savings & ISAs at 5%?

Tax Planning and Financial

 I have 6 properties, most remortgaged at 3%, 7 months ago. We're in our 60s.

Examining our portfolio, I'm now only making a nett yield of only 3 - 4% on each.

Since the personal allowance has halved, and near future capital growth seems unlikely I feel like selling most of them asap ( if they'll sell in this climate).

Then I'd put the remaining money, into long term fixed ISAs and savings accounts getting around 4.5% nett.

No hassle, no stress, no unexpected new rules of large repair bills and more money.

Any thoughts? Is this rash? I know Ill pay more tax. Should I just sell one a year instead?

I reluctantly just want to get out. I've been a good landlord with long term tenants paying well under market value rent, who have stopped me doing this earlier.
