How the calculations, look out this thread

DTI calculation

Hi all, Wondering how DTI is calculated, with the following details. Have a rental property with mortgage X amount. Its PITI is covered by rent. It’s been 16 months (current tenant moved in 4 months ago). Our combined income is Y amount, but ~50% comes from RSU/Bonus. I’ve heard lenders taking RSU amount into calculation, but wonder how it’s done - is it thru W2 for past couple of years? General DTI limit is 45% of Gross Income. Does that sound about right? Given the rental property’s PITI is covered, can I exclude its mortgage from DTI calculation?
