It could also be that the specific FICO models that we use as mortgage lenders are more conservative than the credit card FICO models - which would make sense.

I have seen models that show the two metro areas converging in time, not unreasonable to envision.

Should I start learning how to write up business models to find investors for much larger projects like cardone suggests?

If Ford was still only producing the Model T, it would have been left behind nearly a century ago. 

2 year escrow, 1 year re-model, doors open and business is good.

Every deal and sponsor are different but this is essentially how many sponsors operate - For the sake of simplicity, let's assume a sale has occurred and there are enough net proceeds to repay the LP investors equity in full + their annual preferred return and there is still $1,000,000 of cash available.

But...just because the model works for him, doesn't mean it is what you should be compelled to do it.

I would prefer to buy again in Mammoth because I know the market, have a system down, have a team of people I trust there, but the market is a bit frothy and many properties are way overvalued right now.Also, I bought the place to use it and rent it out, so LTR is always out of the question if that is part of the business model.

If another same-model house has 10 occupants between grandma, grandpa, mom, dad, 4 kids, brother + wife + 2 kids in the same 5-6 bedroom house, why would zoning go out of their way to pick on 4-6 single professionals earning probably 250k+ jointly and being very "green" through their low-carbon living that's kicking their student debt in the teeth?

But I specialize in the lease option model so I attract really quality tenants, however, if the screening is done well for the tenant, I would imagine that the tenant base would be good too.
