How to get a loan if I don't earn much

[Ava G.]

We are currently looking at a $100k condominium unit as a first rental property. We, meaning, my mom and I.

Everything else aside, the agent told us that banks usually loan the amount if the monthly payments are at least 1/3 of my salary (my mom is no longer allowed to loan due to her age).

What we're planning to do is to have a lower equity (say, about 15%) and loan the bigger amount (85%). We'll let the tenant shoulder the balance. However, since the loan is bigger, my salary is not enough to justify the amount we are loaning.

What are the other ways we can convince the bank to give us a loan? Or other ways to finance it?

(As a side note, we are not investing in the US and the market is a bit different so we are considering condos as rental property even if, in general, many do not recommend it.)
