Looking to invest in mortgage fund

[San Eng]

Hi, we have a small family fund investing in Canadian mortgage funds (like a fund of funds) that already put capital in 6 managers. In Canada, even thru this structure we get 8.5-9.5% net returns being passively invested in mortgage funds. The average LTV is <70% on first mortgages. Canada banks are much more conservative than USA and less capital there. Default rates for Canadian bank mortgages are something like <1% vs 3.6% in USA I believe. Lockup is typically one year though if invest larger amounts these can be negotiated.

Are there similar mortgage funds we can invest in to get diversification that pay high single digit returns in USA?

Thank you for any leads or if anyone interested to swap notes pls PM me
