You must issue a Right to Rent booklet which you can print off from the Government website.
You must put the deposit in a deposit scheme. They should be given evidence of this within 14 days.
You must give the tenant a gas certificate every year and it must not expire and an electrical certificate which currently lasts for 10 years.
You must give the tenant the EPC rating letter. You get the EPC done then print the certificate off the government website by entering the postcode and house number.
I give the tenant a checklist with all these documents in a folder and get them to sign and date to state they have been received on the day they moved in.
I also take about 18 photos of each room including the inside of the oven and garden and get the tenant to sign each image as a true image of the state of property when they moved in. This avoids any disputes about property not being left in a similar state to when they moved in. I give them a copy of the photos.
Make sure the contract is water tight. Make sure it states any damage caused by tenants can be deducted from the deposit.
Make sure you include no smoking inside of the property and the garden must be tidied once a month including any grass cutting.
Ensure they advise you if the property will be empty for more than 30 days as this will invalid insurance.
Get them to agree to inform you immediately of any damage or repairs needing doing and not trying to do them themselves as they might make things worse and it could be dangerous if electrics etc.
I also put in my contract that rent will increase each year in line with inflation on the date of renewal of tenancy. I give them 2 months notice of intention to increase the rent to give them the option to vacate or continue to rent at the new rent price.
I would not allow a tenant to paint the house themselves I have all my houses painted white. I do allow tenants to choose a colour if they don't want white but in these instances they must agree to pay for it to be repainted white at the end of tenancy.
I give them a copy of the receipt for a professional clean at the start of the tenancy including any carpets cleaned and oven in the contract they must leave the house with a professional clean including carpets and oven and I require a receipt.
I like to keep things professional and have not had issues with tenants.
If a problem is reported I aim to get it dealt with within 48 hours. The only time I could not get this done was during COVID.
