Maintenance fees can be minimal or expansive, depending on the terms laid out in the association bylaws. I've done mortgage loans for developments where the maintenance fee was a nominal fee every month simply to cover snow removal. Then there are developments with maintenance fees and "special assessments" to cover sudden, unexpected expenses.
Here's what I recommend: get yourself in front of a great, experienced and FULL-TIME Buyer's Agent. Let your Real Estate Agent do the legwork for you. I love the 'net, but when it comes to details like this, and you as a Home Buyer are looking at listings on Trulia.com, you're only looking at ADVERTISING!!! Get a great Realtor to work with you and you'll get the straight truth about any question you have.
Oh, and one other bit of advice: get a referral to a Local Mortgage Banker. Mortgage Bankers in your community will provide you with a much higher quality of service and financing options than any "Big Bank." Local Mortgage Bankers have long been the source of excellent financing options for homebuyers. Further, Loan Originators who work at Mortgage Banks are LICENSED whereas Loan Originators who work for the "Big Banks" are only REGISTERED. There's a BIG difference.
Sit down face to face with your Mortgage Banker to be thoroughly prequalified. The Mortgage Banker will review all facets of your loan request to answer your questions with regards to the types of loans and maximum loan amounts you could qualify for.
Consumers have been led to believe---thanks to huge advertising budgets with the BIG BANKS---that they should go to their bank for a mortgage loan. This is the WORST place to get assistance with the BIGGEST PURCHASE of your life! These BIG BANKS are basically BIG CORPORATIONS. You're a number, at best. With a Local Mortgage Banker you will be treated like a friend and a client for life. You can't imagine the high quality of personalized service you will receive from a Mortgage Banker until you try.
As to price---rate and fees---competitive if not better than the BIG BANKS.
