Multiple loans-diminishing credit

[Randall D Cheney]

If I have 50K to put down on a 200K investment will I qualify on the remaining 150K loan based on the income from the rental or does the lender also consider my job income?  Does borrowing this 150K deminish my ability to borrow another 150K for the next purchase or will the lender give me multiple loans as long as the rental income is there?

Thanks.
