After two years, you can qualify for a loan or continue working the seller-finance angle. 

Commercial mortgages are really DSCR loans.

Private lenders generally have fewer restrictions, a faster process, and can structure loans based on the property’s value rather than just personal income. 

I am planning on purchasing a $350k property with DSCR loan.

We can afford this, but getting a new loan at ~6.5%+ wouldn't be doable. 

Minimum loan size $1,000,000 [bare minimum].

Are there any asset backed loan products that lend in second position or any other forms of financing able to be collateralized by equity you can think of? 

@Leslie Beiai think offering equity when what you seem to need is just a loan doesn't make sense.  

My husbands va loan has been a powerful for your investing.

I'm currently exploring opportunities in the Honolulu market and looking to use my VA renovation loan to purchase a 3-4 bedroom home, renovate it, and rent out the extra rooms as part of a co-living/house-hacking strategy.
