Tenants of a Yonkers co-op building are feuding with one of the owners, who is allegedly trying to auction off parts of the property he has no right to sell.

?I've been living here for three years, and this year has been hell,? says Alicia Guerrero, who recently moved to Buckingham Tower on Warburton Avenue in Yonkers.

Guerrero says she became a co-op owner to buy a piece of the American dream, but her dream has turned into a nightmare ever since most of the apartments were bought by Ben Agunloye of Agunloye Development Corporation. Now, she says, Agunloye is trying to auction off the building?s parking spaces.

?He's trying to sell the rights to park in this lot, which is basically private property,? says another co-op owner, Junior Morelo. ?It belongs to the building, and the building belongs to the shareholders.?

According to Morelo, Agunloye recently placed an auction ad on the Internet, which states that a $5,000 opening bid is required to buy a space that both co-op owners and renters in the building already have a legal right to use them.

Agunloye, however, says that what is being auctioned are "leases" on the parking spaces. Income from those leases will be used to make repairs to the building.

Co-op owners are concerned that Agunloye, who served more than two years in federal prison for embezzling $1 million from investors in a stock swindle case, could destroy their investment as well.

President of the tenants association, Sheryl Newkirk, says Agunloye used abusive tactics against the tenants to force them out, including posting eviction notices and withholding basic services.

Shareholders and tenants have filed a complaint with the New York State Attorney General's fraud division, and they hope the state will step in and take action against Agunloye.

In the meantime, co-op owners and tenants are planning to meet Monday night to map out the next steps in their battle.
