I've done this.I had ~$50k in savings but supplemented it with a $130k HELOC. 

Basically I have a supplemental permit that says SB9 2-unit development, the old house is unit 1 and the ADU is now unit 2.

I know that @J Scott wrote a pretty good book on the process though, (just finished it this weekend), and I would recommend starting with that.If you purchase the book(s) from BiggerPockets (as opposed to Amazon), they come with a bunch of digital files to supplement the material. 

I would need to probably include farm profits in my calculations because the hope would be to eventually farm full time, but also supplement current income till I can move to farming full time. 

But more properties will be needed than buying in cash.Appreciation/equity paydown: Cash flow from rents will be supplemented by property value gains and tenants paying down your mortgage.As a rough estimate, assuming you can buy properties for $150k that rent for $1,500/month with 50% expense ratios, each property may cash flow around $750/month or $9k/year.

I work in Construction Project Management and have found that way more people than I think have found an avenue into RE that has been supplemental income and even a hobby for them depending upon which route they took.

However, if you want 3-5 fully paid off houses in 20-30 years to supplement your retirement, then putting a little more down makes sense so you're not having to fund the property out of your personal cash flow. 

However, just like the rest of REI that is going to depend largely on the are you are looking to purchase in.But if you do the numbers right, in most areas, it's absolutely a realistic goal to find a property cheap enough to have the supplemental rental income cover most, if not all, your mortgage costs.Hope that's helpful!

Our plan is to hold long term (10+ years) and likely pay it off in 5-10 years to act as supplemental retirement income which we plan to get to with a couple more properties paid-off in Tulsa eventually.Would you pull the trigger on these two properties based on our goals?
