Buidling an Airbnb competitor is fine as an idea but the 'no fee' angle isn't a big differentiator. Especially when you say in other comments that you will probably charge fees in the future.
I'd actually look pivoting to building a long-term rental platform where everything is done online (listings, appointment booking, credit checks, contract signing, maintenance requests, transferring a tenancy, etc.). That seems easier than directly taking on a tech giant.
The problem of Airbnb squatters who have gained tenant protections from a sufficiently lengthy stay and then refuse to leave... and needing to go through formal eviction proceedings is a real problem.
