If you shop for an investment property in another state, you want to talk to mortgage pros in those states - expecially in the county where you might buy - because there are so many variations in way things are done & what the expenses would be.

My team and I have done different variations of ADU's small multi, and SB9 projects so am happy to help you further if you wanted to dive deeper into it. 

Sure, there is variations where ones carpet is a bit cheaper and windows a bit more, but the next is opposite, and in the end most wash out to being pretty dang close to par with each other.

That's not the case in Japan, where there is so much variation. 

Acknowledging the market differences between Miami, Florida, and Ohio—such as variations in prices, insurance, and taxes—is crucial for informed decision-making.

That variation can obviously cause quite a significant impact, which is why it is a great recommendation to dig in a couple locations to see if you can find the top/bottom of the footing, or the bottom of the wall (I have seen cases with brick foundations and no footings).

You can find them under Meetup.com under Drinks, deals and meals or some variation of that.

I reckon the "principal-only" repayments (rather than the more usual "interest-only" repayments variation) is the BIGGEST plus for this deal!

For residential properties you have the secondary (fannie, freddie, FHA, VA, USDA or variations that can be held or sold) these lenders may have portfolio loans, underwriting for those will be very similar to the secondary guidelines.

There are many ways of doing this, and a number of variations...at least that I've come up with.
