Good morning Olga. It would all be part of the same application, however there is one borrower, the others are co-borrowers. After understanding income and credit, it may make sense to leave someone off. Tricky sometimes, but if handled correctly they seem to workout.

As others have said, each is a co-borrower and yes, individual credit scores do make a difference in qualifying each of them.   These deals often have other pitfalls so they are not one of my favorites.

I had two twin sisters and a boyfriend buy a property, and the lender had no issues.   

I have done many of these. All applicant's must be qualified. Must add up all incomes and debts for ratios. As a lender in Long Beach Island , NJ I do many deals with multiple families buying a summer home. I do loans in all 50 sates for over 45 years.Contact me.

Sounds like a good question for Joe Petrowsky 

They are each done on their own merit and i have seen a couple removed from a transaction because their scores were low although their bank account large, 

A good question for a lender to answer.  

I had no idea so stopped by to read what the experts said - I may have some clients in this very situation that I believe want to finance

Unrelated buyers impacts the mortgage process far less than the whole issue of how to take title.  For the mortgage, they just look at the whole picture in terms of credit scores, income and debts just as they would for related buyers.  

The same way as if it were for a couple. All the individuals must meet the liabilities and credit requirements. It is just extra work for the loan officer to make sure all the individual qualify to purchase. 

They all must meet the credit standards and are treated equally though the downpayment can come for one or tow and doesn't have to be shared equally.

Not any different than husband wife and son or daughter 

I agree with JoAnn sayng each is a co borrower, but the loan pricing is based on the one with the lowerst credit score.

Each person is a co borrower. Some lenders have a limit for the number of borrowers but most will go to 4.

Very carefully

Carefully, as always. This is common with vacation properties.

Sorry, I do not have an answer for this one. There are those who are more qualified than I am. – M

The others have answered the question.

I never had that experience before outside of an LLC

Each lender has their own underwriting criteria.
