DENVER, Colo. -- Foreclosures. They are the result of the mortgage mess that has homeowners across the country in a stranglehold.

For many Americans who owe more than their homes are worth, missing a mortgage payment or two has resulted in the bank taking possession of their property.

Experts have called the situation a national crisis, but at the same time many are finding new opportunities to invest in real estate.

"I think this is a great opportunity to find some great deals out there," said Gretchen Hoffmeyer.

Hoffmeyer is hoping to find the perfect home and recently took advantage of a unique REMAX program to do it.

Several potential home buyers and investors hopped on the foreclosure bus.

The idea came from the employees at REMAX Professionals, who charge a fee for a seat on the bus tour of foreclosed homes.

The money made is then donated to Habitat For Humanity.

"We're excited at the possibility there's something out there for us," said Hoffmeyer.

Many on the tour around the Denver metro area were surprised at the range in both price and the conditions of the foreclosures for sale.

The homes ranged in price from $140,000 to $750,000.

Some homes needed repairs or remodeling, while others were in move-in condition.

"There's a lot of fear with buyers and investors I think about jumping back into the market," said Realtor Debbie Salek.

She said now is the time to buy.

"If you wait too long you'll miss the boat," said Salek.

When it comes to buying foreclosures, both Realtors and lenders agree you need to work with a licensed professional who has foreclosure experience and can help you navigate the process.

Real-estate experts said there are several things to consider before you buy a foreclosure.

In addition to finding an agent with experience, make sure you have time to invest in the process.

Because foreclosed homes are owned by the banks, buyers must deal with a big corporation. That means once an offer is put in, it could take days, weeks, even months before the buyer gets a response.

Industry experts say most lenders price the homes at rock bottom with little room to negotiate.

They recommend buyers get a good inspection of the property before signing any paperwork, because most foreclosures are sold as-is, and repairs will not likely be made.
