Lewis who here in usa do you know well enough that they can check on the house by driving by it to see if it shows signs of occupancy like lights on at night, tv glow, cars parked in driveway , children's toys in the yard ? (once you have returned to UK ? ) Your LL cant just sit there and refuse to try to re rent it , in more normal times in summer months it should not take too long to re rent and for now the rental market may seem tight only because there are so many evictions in wait, meaning Id bet there are a lot of landlords who will be evicting tenants for non payment or even tenants who the LL really didn't want to renew with but the tenant wont leave , so as soon as states begin to end moratoriums that are now preventing landlords from filing to get tenants out there will be a a huge number of units come on the market . SO for now Id lay good odds the LL would not have a hard time re renting the place .
