If the property is in a condition that prohibits getting bank financing, then your only other real option is private/hard money.

I mostly deal with cash/hard money/private lenders/etc.

thank you @Matthew Crivelli I know most lenders won't accept a second position, but just wondered if a seller or other private lender was allowed as a second position holder on the dp. 

I'm wondering how other investors find private money for a good cash flowing deal.

I stumbled apon a seemingly great deal when purchasing a car from a private seller who was leaving the country.

I wanted to find a property that I could airbnb one unit and live in a private unit.

We put the property under contract with private money; and, I have spoken with some conventional financing options that I have used before that have told me that we can do a delayed closing as soon as we are done.My question, more specifically, is based on the fact that real estate has gone up since our proposal. 

Anyways, a private lender I spoke to mentioned that, if I rent to family, that rental income would not be able to be used for future mortgage qualifications, whether that be for future single family or new investment property.

A HELOC can be used to qualify you for a private mortgage.I would focus on finding flips or a BRRR.

So I believe it's well known that when you're starting out in REI you should start out doing everything as a private person, not a business.
