Hola Coast-Almeria!
From a fellow agent welcome to the forum and to Spain! You gotta be a bit mad to be doing what you ar doing but it sure helps! Hang in there - it will take time to get established but when you do you will be fine!
I have an auction house on the Costa del SOl - when I started it 4 years ago (never been in real estate here prior as had rental agency but was heavily involved in realestate/auctions in UK for man man many years!) I wanted to bring some sensibility to the market.
We were the first to cut the commissions down but running an auction is costly, so we initially pitched at 4% (at the time 7.5% was the norm!!!)
Anyway after the first one I still wasnt compfortable with the rate - bear in mind when I left the UK comms were 1.5 to 1% dependant on sole agency., multiple agency and house price with auctions being .5 to 1% above that! So theory being we might encourage the industry to come down to 3%
So to be bold and bolshy (typical female) we slashed to 2.5% and hearlity advertised it everywhere! 2.5% why pay more was our slogan! Any fees went on replacing the slashed tyres and blown up cars!!! (joke) but we werent popular as you can imagine.
Anyway we carried on with heads held high, numerous arguements with other agencies etc but finally they realized we are not getting run out of town and we dont have the stock they hold as I wont put it on my site unless its a good price (in my opinion) and considering we are in some cases half the 'open market price' we do ok. Really started in response to what I could see was going to be a growing problem with oversupply in the market and with the exception of a few local small guys who do know their stuff, the rest have not a clue and do not come from the old school of EA - ie customer service orientated!
So, having slashed the comm you would think sellers would be beating a path to the foor wouldnt you! nope!!! so dont be disheartened if it takes time, any business over here needs a year to work at it so make sure you have capital to cover you for that time.
And the best of british to you - keep on the forum, Georgia is another agent and there are a couple of others who pop in, Georgia is up by Alicante so you are in between us and in an area neither of us cover but may have clients both buyers and sellers which we can point your way
Keep in touch and enjoy the sun!
