I suspect there is a different mortgage or sales price involved to produce that profit.  

Technically more since you probably don't commute on weekends and they'll be producing more content during those 3 months.  

If I offer an interest only return of let's say 6% for X amount, how can I prove to the lender that I can produce?

Normally I would serve a 30 day notice to quit in this situation.Upon further investigation, it seems the tenants are related to the seller, and neither have produced a written lease yet.  

Yes, you want current income and a personal portfolio, but over the long term, that Roth IRA if invested well can produce a whole lot of tax-free money for you in the future.  

For me it is.Sure, if I went conventional and put 20% down at 4.5%, it would look amazing.But that wasn’t an option for me at the current time.I will have more deals in the future where I can go that route.For now, this gets me in the game, builds a relationship with a commercial lender, gives me experience, and puts a few hundred dollars a month in my pocket, while having none of my own money in the deal.I’m damn proud of myself, because I passed on other deals that I knew would work, but not in the way that I wanted in the present.I needed to pull all of my money out, and I succeeded.Looking forward to placing tenants and get the place producing.

Investing this way (using the same $50k) 4 to 6 more times a year, that produces a 32% to 48% return, or $16k to $24k earnings in a year doing no work at all, and it is perfectly legal.

I also invest in income producing rental properties.

At this point, I'm a little puzzled by the variety of advice around PM-related loan paperwork and who should produce it.
