Detailed Accounting Income Limit

I believe there is a limit for residential property income where total income received and total costs incurred need to be split by property. Are you able to confirm that this is the case and if the limit is £85,000. I believe some MTD for Income Tax software providers may be incorporating this feature. Will you also advise me where I can find full details, regarding the detail required, on the HMRC site as the MTD helpline were unable to locate this information. Thank you
