A lot of condos/townhouses will have large deductibles because they are insuring for large rebuilds. 

The issue here is that with investment rates as they are, I'd have to put more down (25% vs 20%) and then I'd be left with a long road to rebuild or repay that downpayment before I could repeat. 

If the surrounding area has a lot of tear down and rebuild or there’s no inexpensive way to renovate to make it more functional, likely not worth sinking much more money into it if most future buyers will just prefer to tear it down.

Most likely an 'old garage' will be a tear down and complete rebuild.

Once this $50k is gone, it will take years to rebuild. 

I did lose all those wonderful reviews but took screenshots for Guest Book and will rebuild in the next few months.

I don't think there is any amount of savings that could justify the cost of a total tear down and rebuild.

Therefore you can not rehab or rebuild on that property until the year is up.

We are at $400 per sqft to rebuild.

I think a short-term fix-and-flip loan would serve you better because, first, the credit requirements are typically lower than a DSCR loan's credit requirements, and fix-and-flip loans will fund a portion of the purchase price as well as some or all of the rehab costs (usually through the draw process).Right now, saving your cash, rebuilding your credit, and finding both a partner (ideally with a higher credit score AND experience) and lender you're comfortable with should be your priorities.
