He seemed to be under the assumption that we would still need to put 20% down of that 100k.Thank You in Advance   I would go the lease purchase option where you contract a price, pay him monthly rent and then finance it like a traditional loan in 3-5 years.

He still would be visible being that he purchased the property in his name through traditional financing.

You cannot invest in real estate via your run-of-the-mill retirement plan at work or a regular traditional or Roth IRA.You can roll funds over between retirement plans (depending on your current employment status in some cases) but there may be tax consequences if you're rolling over a pre-tax account into a Roth vehicle.Also, if you envision leaving the workforce in the future, you can still have a 401(k) - provided that you have self-employment income, you can establish a Solo 401(k) or a similar QRP.

@Aidan Fox If the numbers work for you to BRRRR with a 75% LTV loan then they work as a flip which is nice because it gives you multiple exit strategies.As far as financing goes, the first two things to get a grasp of is can the house be traditionally financed in its current state and will you be using the house as your primary residence while the rehab is taking place.

I would prefer owning it long term and use the brrrr strategy or should I just do a traditional rehab and flip.

Your IRA is the owner and would be selling the house.There is no current tax consequences.If you have a traditional IRA you will pay taxes when you take distributions in retirement.

Our company is a start-up that is looking to change the way real estate is traditionally done.

Dear Bigger Pockets Members, I have already bought my primary SFH (for living) with traditional bank mortgage. 

We are going to go forward with a traditional 1 year lease and see how it goes and use that time to get a lawyer on our team and see if the tenant is interested in the option going forward on resigning. 

I'm in the middle of my first BRRRR now and I love that strategy, but if you're planning to do a more traditional 25% down buy-and-hold investment, you don't need to limit yourself to just finding a property that you can force some appreciation with a light rehab.
