I haven't used it (yet) myself, but banks can offer you lines of credit for a percentage of your retirement account value.

If rates are still low at bond maturity, they will likely do the former, but they can swap a certain percentage of properties within the portfolio during the term, as outlined in the terms of the debt—in these bonds about 10% of the properties can be replaced to balance the portfolio.So, what about economies of scale?

When I was born here in Vegas in 1979 I was one of a very small percentage of our population that was actually a "Vegas Native".

However, I'm wondering what percentage of my time do I actually have to spend living in the house to qualify for owner occupied financing? 

I also don't recall seeing such a high alteration fee, or one based on the percentage of the renovation budget (It doesn't cost more for the condo's architect/engineer to review more expensive fixtures/finishes).

I personally think if a deal goes wrong and a high percentage of owner financings do.

@Jeremy Margaritondo also not just the loan limits like @Brie Schmidt mentioned, but you also need to be aware of the required down payment percentages (LTV). 

This result approx to 2,500 cash flow after putting percentage aside for maintenance, vacancy, and expenses.

The reason I did the high percentage debt is that hard money folks seem slow and getting cash off the credit card was such a quicker process. 

Most investors don't do this, they only factor in a percentage for CapEx but this doesn't cover the rehab over a 30+ year hold, the CapEx is only covering things like HVAC, roofing, etc... at the end of the 30+ long-term buy-and -hold most of these properties will have a negative or very low IRR.
