Rent added to income for higher loan?

[Ross Ellington]

Good evening BP! I was wondering if anyone out there could give me an idea as to how much the income from a property can play a part in qualifying for a higher loan? My situation is when I buy the property (residential multi-family) can the tenants who are already living there bring value through their rents? Will the lender see that as additional income? I hope I've made since of what I'm trying to ask, if not please message me and I'll clarify. Thanks again in advance for any help. I wish you all the best!
