You could consider using a non-recourse loan for the remaining amount, but you'll need to be cautious about unrelated business income tax (UBIT) rules.

If you have 2 years of landlord tax returns you should be able to count 70% plus of that income.

@Tyler Kowalczik- thanks for the post ....1) get pre approved for a nypotehtical  scenario  so that  you  can make sure you can get  financing and also  so you  can  become familar with the process  2)  you will need a  down payment of  15% or more   3) once you know what a  possible  realistic  loan payment  looks like - do your  reserach on  what  rental incomes  are  realistic  and  this should help with your  decsion making .....the prices are  high in LV ...Port angeles  or  P townsend  might be  better ......consider  Kitsap county  ( although its  been  increasing in value )

So, you still have no idea what their gross earnings are.

They can lend you up to $250,000 towards a down payment if you are a first-time homebuyer, live or work in the county, and meet their income criteria, which I believe is up to 120% of the area's median income. 

Other ideas to increase gross rents: Can you change up your strategy and do a short term or mid term rental? 

As for refinancing or rental loans, you can use DSCR financing which does not look at your income.

Say property owned by “property company” gets purchased by “business LLC” for the new value, which would be a new depreciation amount about 3x higher When refinancing a commercial building that is being rented out, the valuation will typically be based on the Net Operating Income (NOI) of the property.

Look at the current rental income, operating expenses, and potential for future growth or improvements.

This is very enticing after seeing what we would roughly owe on the monthly mortgage even if we are conservative and say we will only make $1,000 a month income from the MIL suite (I think we could easily get $1,500).
