Last May, I came out with my husband to find a home for our family. We have 3 kids under 5 years old. We originally wanted to live in the suburbs - Solln, Pullah,
Grunwald - but in the end found a fantastic place in the city. We got very, very lucky. One thing to keep in mind is that it is hard to find large homes in Munich and its surrounding areas. Lots of expats and very few homes. Every year over 80,000 expats move into and out of the city according to the "New in the city" magazine.
In our case, we saw a total of about 8 homes. The home was either in a bad location (like we saw one gorgeous brand new home but it was not located close to public transportation which we wanted), too old, floor plan did not work for us, kitchen too small . . . We knew that we would not find a home that would be prefect or have all the home luxuries we had back home in the US. So as we started to realize that we were not seeing much we were thrilled about, we opened up to the idea of living in the city. We got VERY VERY LUCKY and an agent that had showed us a 6 bedroom house in Schwabing told us about an apartment (penthouse floor) that just came on the market in
Lehel (literally the tenants had just given notice). I've been told that Lehel is the first housing area (village) that was built outside the inner old city of Munich (just outside the ring). We saw this place and loved it! It is about 3000 sq feet, a few blocks to the Lehel substation, a block to the
English Garden, supermarket and bakery and pharmacy close by. We even have a parking garage so we don't have to worry about finding parking on the street. The large size American size fridge was also a plus. This place of course was not cheap but well worth the extra cost. Rent plus utilities is over the 2500 Euro allowance you mentioned you had.
Most of the homes we saw were in the 2500 to 3000 range plus utilites which usually are about 10% of your rent. We originally wanted to live in the suburbs in order to get more space / an outdoor garden / play area for the kids. Living in the suburbs would allow us to be close to the kids international preschool and MIS which they would eventually attend. However, it would make my husband have a 45 minute to hour commute. By living in the city, my husband has a 25 minute door to door commute to work (Nymphenburg area) which is nice since he works long hours. The kids and I have a longer commute to school - 30 minutes to the suburbs. Evenutally when our kids go to MIS their bus commute will be about 45 minutes to an hour but lots of kids who go to MIS live in the city. They have big buses pick them up all around the city. Now if you live in say Solln the commute to MIS is about 25 minutes.
If you live in the city you tend to enjoy more of the city and the life it offers. People I know who live in the suburbs tend to stay in the suburbs.
Also something to keep in mind is that the suburbs do not have the extensive public transportation that exists in the city. Like there is only one tram that goes in and out of Grunwald. So by living in the suburbs you would definitely need a car or TWO and cars are not cheap. A fully loaded brand new Mercedes station wagon would be about $60K in the USA but here in Germany it would cost about 75K euros with tax. Buying a preowned car is your best option unless your husband gets a company car benefit.
In terms of cost of living, eveything seems expensive to me as an American. Sales tax is 19% and of course the exchange rate (Euro to dollars) does not help. Like I bought my daughters two Polly Pocket toys that back home would of have been $45 but here it was like 60 euros. If your husband's company adjusts his salary for cost of living and equalizes him for tax purposes then what you feel you can afford should not change. Tje other day I went to the supemarket and filled a cart with groceries. Total price was about $400 dollars - bought a few American luxuries like Haagan Das ice cream but otherwise basics like fruit, veggies, cereal, coffee, deli meats, eggs, soda, juice, pasta, etc.
Feel free to PM me back if you have specific relocation questions. But as someone else said, there are lots of expats here that are always willing to help and share their experiences / advice
