Buy a house, rent it out, renters pay for your mortgage, whats the catch?It seems like there are many properties you can buy and then rent them out and make money. For example Buy a $125,000 3 bed 2 bath house in Sac. Zillow says Monthly payment will be $771 with 10% down, inc. tax and ins. I could reasonably get $1100 for rent. Let's say the house is vacated once a month and I will add $50 for expenses per month. This still is a positive cash flow of $3,948. Am I missing something, whats the catch? Are people not doing this because the difficulty with a down payment?August 26 2009 - Sacramento00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
