If you’re looking for quick cash for your house, you now have several apps to choose from. The business plan for these apps are interesting:

Think of them as house-flippers that work for you. Sellers fill out an online questionnaire, and an iBuyer uses proprietary modeling to assess the home’s value. The company then makes an all-cash offer within 72 hours, sight unseen. (The iBuyer keeps a 6 to 10 percent commission off the price.) They make light renovations and relist the house at a markup. Home buyers can browse and make an offer via app.

It will be interesting to see how much participation these apps generate. There’s a lot of VC money behind these startups.

Little Steven gets in the social media act.

Steven Van Zandt, an actor and musician known for his turns on “The Sopranos” and Bruce Springsteen’s E Street Band, is launching a music-themed social-networking site that he said will serve as a hub for insider information and advice directly from bands.

The site, Fuzztopia (currently in beta), is expected to launch in three to six months, Mr. Van Zandt said, and he is looking for funding in the low eight figures to get “from the present tense to the future.”

Given his passion for rock music and all of his connections, this idea seems plausible. MySpace currently dominates the playing field in music, but there should be room for another player.

Mint.com offers free online tools to manage your money, and it’s been a huge success. Intuit decided to pull the trigger and buy it.

Intuit is buying Mint.com for $170 million in cash, in a deal that gives it control of a startup that had disrupted its dominance in personal money management software with a free online alternative. Intuit, which sells Quicken, and Mint had been in a tight race in the online personal finance market, with both companies claiming more than one million active users of their online products. Last fall, Intuit dropped the $2.99 a month subscription fee that it was charging for Quicken Online, partly in order to better compete with Mint. Intuit says it will now offer both services separately, although it says Mint will be the “primary online personal finance management service” it will offer to consumers.

Both sites make money by referring users to financial services like credit cards and credit counseling services. I guess the free service model still works!
