I recently got through with a rental managed by RESYS and it started out well with the rental agent showing the house and being very friendly and accommodating. However, the house was not cleaned very well and after move in I discovered several areas that needed a thorough cleaning - namely the bathrooms and kitchen appliances (stove especially). Throughout the lease there were various repairs that were needed and it does take a few days for them to contact the owner and get approval - so although they do get done there is definitely a delay from when a problem is reported and when it is serviced. My biggest complaint is upon my move out there are extensive clean-up requirements such as professional carpet cleaning (that you must show a receipt for - approx. $275) and providing utility bills for all utilities showing there are unpaid balances, etc. I performed all of them, yet was still deducted over $200 for a cleaning deposit after having the carpet professionally cleaned and a maid service do the rest - leaving the house in much better condition than when they leased it to me. So, if you are considering renting a property managed by them be aware of these issues.
Also, they moved to Rainbow/Alta - they are no longer on Edna.
