We were in a similar position, needed to love quickly, didn’t sell in time so rented instead of selling.
Things to think about
Keep money in a separate account and don’t touch it so you have a reserve to fix issues
There will be A LOT of issues.
Get a decent letting agent to manage the property and apply the law correctly. So many landlords don’t know it
Remember you’ll be liable for capital gains tax
Get an accountant to do your tax return. Lots of things you can deduct that aren’t apparently obvious.
Don’t expect to make much money. After 5 years as a LL, we will be doing well to break even. It’s absolutely not a money spinner
Let the property in the state you want it back in. We had carpets professionally cleaned, cleaned the oven and it was absolutely spotless when we let it.
Don’t forget you’ll need to convert to a BTL mortgage or a the very least get permission to let from your lender.
You need landlord insurance.
And a gas safety certificate (letting agent will sort this)
And electric safety soon (next year I think)
And smoke alarms. And CO detectors. (Letting agent can advise)
Good luck!
