I have 20 years experience in holiday rentals, but only 6 on airbnb (much more challenging than my past 19 years experience I must say).
In my experience long term rentals are costly and risky.
People get installed, really use the kitchen, will complain about any amenity being out. If they are there for 4 days or one week, they will probably make do, eat out, not use the laundry machines, not use the kitchen, not move the furniture.
Long term stays want extra linens, they will need perfect internet and TV during their whole stay, they will not let it go if something is not working properly. They will make themselves at home and move stuff around. They will make intensive use of your machines and appliances and stay home more than short term rentals.
My property managers INSIST on mid-stay checks when a longer term rental is in there.
The potential for filth and damage and just all around inconvenience is much higher.
Yes you save on not having the property turn over as much, but on the other hand we’ve found damage and usage much higher.
And especailly beware a long term rental at full capacity or above capacity. It’s a huge difference if you just have a retired couple or if you have a family of 5 with kids.
In my experience, longer stays want: lots of extra linens (for no extra fee), cable television service (impossible for us we have 56 nationalities and languages each guest wants TV in his language), impeccable internet if it’s down they don’t just make do, theyll stay in more go out less and use everything much more.
You also have to be very careful in your area about staying times and when the person can become a resident in your house. We had a home in France and a person wanted to stay one week more than the 3 months allowed for holiday lets. That would have enabled them to elect residence in our home and it would have been impossible for us to expulse them. I am convinced this was their plan and we didn’t fall for it. So check your local laws.
I think you might be better off paying someone to manage welcoming your clients and doing the cleans, and keep the short term rentals.
