It seems like a hard money lender typically a private individual or venture firm) would be the only route to go since they are a little more lax on lending requirements than a conventional lender.

If it's HOA/Condo vehicle requirements you're worried about, it's usually already in a standard lease that they follow those; otherwise, they'd probably expect tenant to comply with city codes unless there's a viable reason an owner wants something more strict. 

When I self-managed C Class properties, I would put the requirements for tenancy in the rental listing (3x rent in income, 1-month security deposit, criminal check, etc.), and then when the potential tenants called in, I would speak to them for a few minutes, explain the requirements, get some sort of verbal confirmation on some or all of the requirements, and then invite them to different showing times I had set up.
