My understanding is the mortgages are no longer offset against tax so Landlords are no longer able to deduct any mortgage expenses from their rental income causing a large increase to tax rates.
That's not correct. Mortgage
interest (the capital payment of mortgages has never been deductable) used to be claimed as a direct expense. Since 2017 this has slowly changed until now that the mortgage interest is given a 20% tax credit.
For a Landlord who is only in the 20% tax band then this has made no difference, for Landlords who are in the 40% band and higher, yes it has led to higher tax bills on their profits.
Furthermore the government wants energy efficiency levels to improve which I am not against in principle, but they are going about it the wrong way. So landlords are expected to get all properties up to a energy grade C by 2025 which means doing things like spending upwards of £15,000+ on things like a £6000 solar panel water heater to save £32 a year. Which just does not make financial sense. Sure some of the fixes are reasonable like making sure all bulbs are LED but things like fitting a solar water heater to get the energy grading up are just silly.
It's by 2025 for new rentals or 2028 for exisiting rentals. And yep, this one is going to hit me with my one house, as it has a multifuel (coal or wood) backboiler as the heating system, there is no mains gas available and electric immersion heater. So the only option is oil, which are being phased out anyway iirc, or heat pump thingy which are lol money.
In this thread we seem to be running off rent at £200 above mortgage which is £2400 "profit" a year unless your one of the delusional posters that think landlords are immoral and should be renting at cost! The problem is the tax bill is now £2600 ish before expenses for a typical property so we are on -£200 from that £2400 profit. Then we have all the services and expenses the landlord has to cover which can push that to -£1000 a year. Then the landlord is now expected to find and fund what is many cases is £15,000+ worth of work on -£1000 yearly loss. This doesn't even cover building up a pot of money for repairs, refurbishment e.c.t
I posted this not aimed at you. Someone in this thread a few days back asked why are landlords are selling up even if they are on a fixed low interest mortgage rates and have a easy time of things. This is why. Its not as easy life and this is why a large amount of landlords are trying to get out before 2025. Its looking like many Landlords will be running at up to a -£16.000 loss in 1 year if they try to meet the new rules.
As a counter, you are not looking at the rise in asset value of the house from the improvements and the general appreciation the house will have over that time. You can't really look at a capital investment of that size and say "look, it makes a loss" that year, as either it'll be capitalized and claimed over time as a write down allowance or (as i haven't looked into it yet) it won't be an expensible cost anyway and will be claimed against the CGT when you come to sell the property. Capital expenses on houses get treated slightly differently than in normal businesses.
