Building on the extra lot makes the numbers work for the whole deal, from the cost per SF new construction I've seen floating around. 

For example they took on (a) floating-rate debt (instead of fixed rate which was more expensive but safer), (b) short-term debt (cheaper but then they ran into refinancing problems) and (c) high levels of debt (to try to juice projected returns rather than conservative levels which aren't as "exciting" to a certain type of investor).

You can install those floating shelves to maximize space which also people to put their detergent and cleaning supplies.

Falls into the "wadyagonnadoaboutit" category, but the fact that they are making money on the float off our properties and guests, in addition to high fees, is frustrating to say the least. 

It almost certainly will.I'd encourage you to focus on more than just cash flow, because you most certainly have the income to "float" the difference until it does cashflow better!

With that much income, I'd have the vague suspicion you should have enough cash of your own to do the deals, or maybe just need a much smaller loc, say $50k, help with the float/cash flow.Also, since you are flipping, you don't have any collateral and you are extremely market dependent on finding deals.Try and see. 

Carpets and floating laminate can be deducted at once.

Don't let the gurus floating around tell you that you have to fix and flip or buy multifamily to be a real estate investor.

Ideally I could breakeven YoY for the first few years and not float too many costs so I can continue saving and investing.

Or they could go up and cause more profitability issues (especially if this is floating rate).
