Yes the Class feature Cost a bit extra which is a bummer bet the support for it is amazing, and it is easy to allow access for Tax Accountants to pull the reports they need rather than my clients playing middleman. 

Usually its a safer bet.

Your best/safest bet would be a regular lease combined with an option to purchase.

I know it's not as flexible as a HELOC but as long as your deal flow is good and the tenants are paying the mortgage you won't come out of pocket for it. 

@Will Greenlee there is no perfect PM software, unfortunately.We use one of the most flexible, but it has a long learning curve and we'd still like to see many improvements.

This gives you flexibility and a clearer understanding of how you’ll proceed based on market changes.

When you’re flexible on the terms, you can often create a deal that satisfies both parties.Create a Sense of UrgencyIf you want the seller to move quickly, create urgency in a respectful way.

That sounds like a lot of work and I'm sure he would prefer to avoid that work and just sell it for $1.9m or $2.0m.if I were to buy it from him, to get to cash flow neutral I would need to increase rent on all 6 units to market rates and my monthly payment would need to be close to $6.2k/month, which would be $100k down payment, $1.7m loan with seller financing at 2% interest rate and flexible ballon payment.What would you do if you were me? 

It is flexible though, in that I can roll it into any IRA at any time.
