A bank has its own loan products and may have some other products they broker out or sell on a correspondent line.

In today's market, rising interest rates and economic uncertainty might favor holding properties for stable cash flow, while flips could be riskier if buyer demand softens.For many, a hybrid approach works→ flipping in strong markets and holding rentals for long-term stability.

There might be a product you can treat the line with to help slow the process down. 

You could buy a house with siding made of corn cobs if you'd like and they'd finance that (assuming the corn cob siding passed code).The issue is that true log cabins tend to significantly limit buyer pools because they are a bit of a niche product so lenders don't want to finance them at all due to the added risk for resale. 

Education, financial stability, strategy definition, team building, and thorough property search are essential.

@Tyler Kesling   Fannie/Freddie do not have a "blanket loan" product.

One visionary comes up with the idea and creates an ingenious product, but later generations will always have the advantage of hindsight and trial-studies from which they can improve their design.It's very difficult to say where the whole space will go.

I'm not that familiar with FHA 203k, but if you can a lender that offers that product, they'll be able to talk through it and see if it's possible.  

@Adam ZbiciakI've been pricing these in the high 8's and low to mid 9's for most scenarios, similar to as you've described here.If you have a larger loan, stabilized with good cash flows, strong experience with 9+ properties, and strong liquidity, I've quoted these in the 5's (at par) at 55-60LTV with a Family Office I work with.
