Dear Kindly Kansas Condo Hunter:
Its great to see the response you've gotten to your request. There are some really experienced pros that provide advice on Trulia, that may be able to spot trouble and help make the transition a good one.
In addition to the legal info I cited, there are some other points to consider:
1) Home inspection -- get a real pro, which may cost a bit more but be worth it. Note that there may be information on file also at the local public works department, that might spot trouble with local sewers or other drainage problems.
2) As Ms. Greer mentions, the Master and Unit Deeds are informative. The Registry of Deeds for Saugus is listed at the link below. Information on the condo developer, management association and trustees can also be gleaned directly from the Registry and possibly the MA Secretary of State Corporate website. Its always good to know how many relatives or business associates might be controlling--directly or indirectly--the condo decisions. Also, this is a great way of learning if some of the condo sales prices might be inflated. Be mindful of any sales where a second mortgage was provided by the developer as part of the sale, and then shortly thereafter recorded as paid in full. The sales prices of the units can be falsely inflated by such creative financing.
3) Do have a good, independent real estate attorney review the condo Master Deed. There are some very curious Master Deed Condo docs in the Registry, that seem to require the condo owner to sign away the right to sue the trustees or management company for contracting for services which may involve self-interest. This includes their hiring a relative or an associated business in which they have an interest. As part of the condo fees, you deserve to not be overcharged for repairs that may be of benefit to those empowered to supposedly act on your behalf. You would probably never knowingly signing away the right to even challenge overcharged services that may be benefiting the trustees or developer.
Good luck with finding your new home.
