In terms of what you should run numbers for regarding taxes I would always run them with the assumption that you will be assessed at the sales price as that can be the case.

POS assumption in Shaker Hts has 200% escrow.

Back in the 70's they did it all the time but called it assumption and depending on the lender may or may not roll the loan into their name so if they are older mention this.

Of course there is no data shared so I can't confirm or dispute the underlying assumption there. 

Then you will make some assumptions on your debt financing, subtract that and you will come up with "Levered cashflow"Income-Expenses=NOI-Capital Expenditures (renovations)- Acquisition Fee's= Unlevered Cash Flow - Cost of Debt= Levered Cash FlowThe levered cash flow is the number you will want to use to calculate any returns you are able to pay investors.

. - How do my assumptions look above based on the market? 

Run your numbers and be realistic, don't make assumptions.

Rental appreciation is riskier than cash flow - but is a reasonable assumption if you have a property that is located in a desirable area and has advantages compared to other properties in the same price range.While the cash flow on this property or a similar one, won't make you rich - I think you have a lower chance of a 100% loss than you would with a 2% 30K fixer-upper in the mid-west.Even though you are dealing with a high cost area, you still need to push for a discount on the property.  

The lawyer makes the logical assumption you own the LLC as a way to shield yourself from liability.

@Michael McgheeYou are correct on a few of your assumptions.
