Putting that little down on a multifamily property will likely not work for most lenders (especially 5 units and up) with DSCR ratios being difficult with interest rates so high. 

Most agencies are slow to process paperwork, have a lot of bureaucratic red tape, and it is difficult to get them to respond to inquiries.

Third, you will almost certainly need to hire a STR management company if you buy internationally which often makes the numbers difficult. 

However, if I tried to sell this note, I might have a difficult time doing so because there is no open market for selling notes and adding the fact that the note is in default, I might have to discount the note if I wanted to get cash for it.

Once a month may be difficult for some borrowers and lead to strain on advancing the project.

I am under the impression it is very difficult to get lenders to finance new builds especially spec builds.

Otherwise, it's very difficult to find a property that is cash flowing well.

If you use different sources it will be difficult to calibrate the different scores, but think of it as a percentage of the max available score.This particular score seems to be based on an applicant's credit history, including payment history, credit utilization, and credit availability. 

I don’t think well maintained, well run properties that have rents at or close to market value should ever be that difficult to sell.
