@My2favboys you’re welcome. If you would struggle to cover both mortgages ( if you get a non paying tenant or there’s a problem with the property and you can’t let it ) then you really must take out insurance. It’s usually about 1.5- 2% of the rent but there’s lots of Ts and Cs and you’d probably need to use a letting agent ( so that’s another 10-15% of your rent ).
Plus of course your contents and buildings and liability insurance, ground rent, legal fees, mortgage fees, mortgages, compliance costs, voids, repairs and maintenance.
Void costs can be quite high. With the Covid rules you can’t show a property until the tenants have moved out. So you go on day one, have it redecorated / any other maintenance like replacing carpet or worktop, new appliance etc . Say that takes a week .
Then you photograph it, advertise it and do viewings on week 2 and the first person takes it. You need another week to do all the tenant checks, so that’s week 3. Then they give notice to their existing LL, so that’s another month.
So your flats been empty for 7 weeks and you are paying everything as usual PLUS the gas, electric and council tax. Then once the tenant starts you lose perhaps half of the first months rent on expenses .
So that’s 9 weeks with no rent and you are paying lots of extra costs for 7 of these weeks. So maybe the equivalent of 10 weeks without rent.
And that’s assuming there’s no damage when they leave, it just needs some decoration etc.
And you need to have spare cash in case something like a boiler or water tank needs replaced.
Your mortgage lender will have their own figures for how much you can borrow compared to your gross annual rent. They will probably want your rental income to be at least 125- 130% of your mortgage.
They will also stress test it at 5% ( to make sure you can still pay if the interest rates go up ).
You will only be able to borrow 75% LTV on your BTL property ie you need 25% equity.
Ane one of you will need to earn a minimum amount, perhaps about £25,000.
But each lender has their own criteria and of course they are stricter for inexperienced landlords.
There’s a lot to it - it’s not a license to print cash as so many people think. So you are doing the right thing to work everything out now to see what’s the best option for you.
