Hi - looking for advice on best practice in how to handle a situation.
Current tenants moved in Jan, a couple with a little boy. Two bed flat. They have paid on time and are generally good tenants, some issues with cleanliness but after 6 monthly 3rd party condition check they have improved.
They are foreign nationals but all correct RTR checks etc in place. They have advised they are pregnant with another child due December and that due to lack of support network here, they would like to bring mothers parents over to help with birth, arriving Nov and staying for a couple of months. The mum to be works for the NHS, dad uber.
All reasonable enough, from a human perspective. It’s not massive flat by any means, and previous tenants caused significant damage by subletting to multiple extra people without consent, so I am wary of facilitating natural extra ware and tear from two additional adults, but also don’t wish to be unreasonable/over bearing in trying to get more rent etc at a time when money will be tighter; having literally just had a child myself.
What is accepted best practice in this situation, on both handling legal/documentation side, and also just any advice generally. I have no reason to distrust the tenants or assume the worst, but obviously my previous experience is fresh in my mind.
Any help or suggestions greatly appreciated. Thank you.
