I am managing Amosfera Coworking (www.facebook.com/coworkingamosfera?fref=ts) space in Split, Croatia. Few years back, I have worked for a local real estate agency for a month so I got to see how it works from the inside.
Outside the tourist season (July - August), you can get a two room apartment of 50sqm next to the city center for anything between 300 and 500 euro, depending on the location and the quality. This is average. Split has lot of apartments of rent which are usually used by students throughout the year. This means apartment owners try to rent for the whole year, and since it’s students, it’s cheaper. Much cheaper than Airbnb or during the tourist season. 1000 euro per month should buy you a 70 sqm apartment in Peristyle (www.visitsplit.com/en/528/peristyle-peristil).
Also, the best time to look for an apartment in Split is September. It’s before university year starts and 10 000 students come rushing into the city. If you can choose, and you are going to stay here for few months, my suggestion would be for you to come to Split anytime between 1st and 15th of September, book an apartment via booking.com or any other service provider, go to local real estate agency and get them to help you find an apartment.
Usually they charge one monthly payment (the agency), and the apartment owner asks for you to pay on month rent upfront as well as the damage insurance which is usually the same amount (you get this back if you don’t damage the apartment). So if you are taking an 400 euro apartment, it will cost you immediately 1200 euros.
You can as well try finding an apartment by yourself and saving yourself the agency provision. What you can do is find postings of available apartment in local facebook groups of classifieds (better option). Most often local people who need to rent an apartment in Split use local newspaper classifieds Mali oglasnik (online version is available for purchase here: trafika.slobodnadalmacija.hr) where virtually all the rentiers advertise their apartments.
Just be aware it might take longer time for you to find an appropriate apartment, and this gets stressful and tiring. Most probably you will have to check more than 5-6 apartments to find the right one and this takes couple of days.
Last couple of months I have had few DMs asking for help finding an apartment (sorry for not seeing this thread before! ) so I was considering getting this as an additional service by our coworking space. If you are interested in using a coworking space and need help finding an apartment in Split, please don’t hesitate to direct message me. I will be more than glad to help.
Hope this helped.
