I don't know, a couple of hundred dollars within a few months can be a normal expense for me. I am a out of state investor and some quarters are better then others.
August: Electrical, $75 service call.
Sept: Exterior stucco repair $250.
Oct: Landscape $150.
My PM has a $500 limit before he has to call me. The way I see it if he spreads $500 over 6-8 months to keep the place from falling apart while he keeps it rented. Then it is $500 well spent towards my investment.
I also require him to send me pictures once a year of what has been completed and future repairs that may need to be attended to. Sometimes $600 in upkeep is identified, and I have him spread it out over 4 months.
Also, maybe you should look into a good maintenance protection pan, this may cut down on some of your cost depending on the service call amount. charged.
Are call around and get quotes on the repairs that have been done; for comparison of what he is charging you.
hope this helps a little, good luck.
