How to win against "Cash offer"?

[Kenny Tan]

Seeking advice on creative financing. I am trying to help Sister-in-law family buy their first home. Their income is around $50K last year. We will help them with their savings to make 20% down. Basically gifting so no repayment expected. Their loan broker said they were pre-qualified for $480K house purchase. They made 5 offers all over asking price, cash buyer or huge down offers beat them.

I am thinking what other creative strategy can we use?

1. 1. Delayed financing. We borrow money make all cash offer. If accepted, have them refinance and pay us the loan. It sounds risky, can it done? Did any do this, not for your own house?
2. What other method can we use to bring more cash to the table?
