We offer traditional types of funding as well.

But I love talking about Subject To, also called Sub2 & Wraps, Land Contracts & Lease Options which I think have bigger bang for the buck than Fix & Flips or traditional bank financed Buy & Hold Rentals.

I swapped my traditional 401k over to a checkbook 401k and am anxious to park some money but am struggling to make that first move. 

And yes I've seller financed RE too via traditional Note and Mortgage (security deed).But I sell on land contract / contract for deed (the same) as well when:- deal price is so low that the closing costs ($2-3k) is an unfair expense for the buyer to pull out of pocket

A Solo 401k can have several "subaccounts" including both Roth and traditional pre-tax funds.

We're really trying to avoid doing a traditional loan, and don't want to commit to living in the place using an FHA loan.

If so, do you check off "Other" and list "private financing" (as obviously this isn't a traditional mortgage)?

It would be ridiculous in my opinion to demand one on a property that I didn't bring to the buyer.That being said, I am doing my own form of off market farming, but more of a targeted-area traditional MLS listing AND/OR potential off-market deal, depending on condition as I am completely mentally exhausted and done with my service business that currently pays my bills (and wastes my time :) ) and have a burning desire to replace its income with RE commission ASAP so I can roll up my sleeves and start building a RE empire full time. 

Buying it traditional can save you on interest rate but heloc on the other hand is not fixed rate, as of now my heloc is reaching 6% flexible rate.

My wife and I have been working under the idea of starting ourselves out with hard money, as we a) don’t have the best credit, and b) don’t have much of our own money to go traditional routes.
