@Jiwei Yang it all depends on the property, the appraised value, the income it generates and finally your experience and financial strength.They will use the income from the property to service the debt but they will still be looking for you to guarantee the loan so you will need good credit, income and assets including cash reserves.

Thank you @Chheang Yang and @Kevin Hill for the response.

But there’s a yin and yang to everything.

Thanks for the welcome, Kerry, Joe, Mike, and Yang.

Leon Yang no capital gains if he stays there 2 years as is his primary residence. all of the profit is tax free.he's basically breakeven on the rent & he has no savings. he'd have to rent a new home to live inas he wouldn't qualify for another loan cuz he can't include the rental as income & he doesn't qualify for 2 loans with their combined income.

As for your question - Leon Yang wrote an awesome post about this the other day.
