You wil also want to read the HHHHOA arrement to see if there are any oher asssments in it for extrardinary csts.. For intance some communiies own their strret lights and if one need to be rplace the agreement may require all the members to pay a share of the cost in addition to the reqular fees.
There will be a Home Owners Association and they can give you a copy of the agreement that spells out the fee and what it pays for. e.g. paying for costs of maintaining the communiy pool/recreation area, mowing and plantings of common areas etc. Taxes are separate and not included.
