Many directors believe that having an extensive portfolio will make them a more viable mortgage applicant - but this isn't necessarily the case.
Landlords are essential applicants who may have multiple investment properties making up an extensive portfolio.
If you have multiple assets and numerous loans or mortgages, this can be a negative as all your income and outgoings need to be included in the affordability assessment.
Some lenders also have caps on debt exposure they can offer, so even if you make significant profits, they might not be able to lend if you have large mortgages elsewhere in your portfolio.
