Use Rental Income to Qualify

You can use 75% of actual rent to add to your income qualification.

For example, if the property has a two tenants who pay $2,000 each, that’s:

$4000/month rent x 75% = $3,000 qualifying income

Income Qualification – Example

Let’s say you have $8,000/month gross income and a $500 car payment.

In general, your income qualification is about 45% of your gross income, minus any debt.

$8000 x 45% = $3600 minus $500 car payment = $3100 income minus debt

You can also use 75% of your rental income to qualify. In this example, the two renters of your future triplex pay $2,000/month each, or $4000/month total:

$4000 x 75% = $3000 rental income

$3100 + $3000 rental income = $6100/month total housing payment

Housing Payment Example

Quadriplex – $1,995,000 purchase price

5% down payment = $99,750

95% loan amount = $1,895,250 (falls within superconforming limits – non-jumbo)

Principal & 7.5% interest payment = $13,252 + $600 PMI + $2500 property tax and insurance = $16,352

$16,352 payment minus $9600 rental income = $6752/month payment. Similar to buying an $800,000 home, without the tax benefits of owning investment property.

Current rental income: $9600 x 75% = $7200 income towards qualification
