Recently bought my primary home 7 months ago with 3% down, and I'm looking to buy a 2nd home(investment) for little money down...my credit is solid, I've hear that banks require upt to 20% down for rental properties...not a problem, but most of my cash is tied up in investments....Is it possible to leverage my credit for a very low down payment? or should I look to take out a home equity line of credit against my primary property(don't believe I've built up enough equity) or should I take advantage of these two 0% offers from my credit cards, buy the property and take advantage of 0% interest for a full year...The answer seems obvious, but I'm a newbie at this, so I'm looking to get some input from the troops.
