Buy Now, Move in Later?

Redfin readers David, Michelle, Dave and Red had some great insights on the idea of buying a house now as an investment and renting it out. This can seem mighty tempting, considering that rents are higher than mortgage payments in some areas, fellow blogger Alison Ching pointed out, but it’s not that simple.
(Though, in answer to one David’s comment about rent control: People move in and out fast, at least based on reports from a landlady friend of mine. Every time they move out, you can raise the rent.)
What about this idea from another commenter: Buy now and move in later? That might be a way to take advantage of low mortgage payments and higher rents.
One drawback: a change in the new housing bill just signed into law could affect people who purchase second homes or rental investments with an eye to moving in later. The bill narrows the use of the code’s tax-free exclusion allowing sellers of principal residences to escape taxation on the first $500,000 of their profit (married joint-filers) or $250,000 (single-filers), real estate ace Kenneth Harney reports.
So, readers, what do you think? Is it worth buying property to rent now and live in later? (Photo: merfam on flickr.)
