Unless the current tenants did some serious damage in the 6 months they have been there (which I doubt), this should be a fairly straightforward turn (though new tenants are flexible on move-in date if it turns out I need more time).  

If you are able to make Roth contributions to a Solo 401k rather than a Roth IRA, you can maintain more flexibility.

There is a certain health ratio for restaurants after food and labor costs.You need to figure out what you want the ground rent to be based on all the costs involved and how long you want to hold the property.Generally the longer the primary ground lease the more value it can have for resale unless the tenant want given a sweet heart deal with little to no rental increases.What tenants often want is FLEXIBILITY in termination clauses and short primary terms with options.

I know that the equity is the most important factor, but if the ROI is great, and the purpose of the Sub 2 is a long term buy and hold strategy shouldn't that make the formula more flexible, since the equity would build faster with a higher ROI?  

If your job is flexible then it's a good way to get started but if not it can be more difficult.

As @Derek Dombeck said, there are different structures to know and be educated on, but even the details to those are flexible to what makes sense for all parties.

If I keep money in and they don't, then their % ownership will (albeit very slowly) be diluted continuously.In addition to using the cash flow of the LLC's first investment to save up for new purchases, I'd like the flexibility to add new investors.

Now that you're financially more flexible, I applaud you to turn your attention into investing.First, I'm assuming you are referring to 5 or more unit properties, since income based valuation is largely irrelevant when it comes to 4 or less unit properties.

Many of them prefer the LOC against the equity of the homes as opposed to the commercial notes as it can be more flexible, but I don't believe the terms are as good.FYI, the commercial notes generally have worse terms than single mortgages.

You are more flexible with your hours, since you are your own boss.
