I only do tenants with bank accounts that can do ACH pay via erentpayments.com / cozy.co ...Think outside the box in mid-GA, only buy quality houses in growing MSAs with available jobs. 

However if he is looking for all the money now and or soon you can look into finding a money partner who has the funds and you can purchase together with an LLC/Joint Venture.

Also, I am reading about syndication and joint ventures.

Leverage a more extensive network and the economies of scale and rid yourself of the head aches.

If you or your fiancé can qualify for financing on your own (not jointly) for either the primary or investment, it would be more beneficial to do so.

There are also NCNDA, Joint ventures, option agreements, addendums, etc. 

Alternately put together a friendly joint venture - where your friends or relative agree to contribute X $ to be used for real estate investing.

Then step a) go with regular concrete and “shark bite” paint (basically sand added for grip) and then step b) put expansion joint covers over the joints and slant it all towards a drain.

Of course just like any other joint venture in real estate there's a risk that he takes your money and turns his phone off and you have to go through a long legal battle to get your money back - but is that what it seems like to you?

If the property is the security for the loan and there is a shortage, the LLC may very well be liable, and well as you two personally up to the full amount of the shortage for either of you, assuming liability is joint and several.
