Its a tough subject because logically, they are joint and several guarantys so rationally a 100% guaranty from each of two people (one 740 one 680 for example) is ALWAYS going to be better than just one 100% guaranty from someone at 740 (so it wouldn't make sense to have a better rate for the latter)The problem is that there is fraud and "straw borrowers" out there where someone who is not involved in the property signs on to boost score and terms - so many DSCR Lenders in response either do the "non-rational" thing and price to the lower to avoid the fraud or use the higher of the two (and either be a little loose with things or just stay vigilant on any funny business)

It can be tough to make money with high leverage, especially if market conditions change.

Personally I think it should be a legal requirement for the reasons detailed above, showing comprehension for the legal contract there entering by proving consideration and thought has been made for potential exit and dissolution of said contract.

However, the approval process can be pretty tough, especially if you're working on a larger project or have a shorter timeline.Private Lenders: These options are typically much faster and more flexible, which is key when scaling development projects.

In some cases, Fannie Mae may approve a PMI removal even earlier than the 2-year seasoning period if you can prove the substantial increase in the property’s value.Speak with Your Lender: Given the complexity here, consider having a direct conversation with your lender and asking for a specific review of your PMI removal request based on the current LTV and any potential reappraisal opportunities.In summary, while it’s generally required to wait for the two-year seasoning period for PMI removal on HomeStyle loans, there could be flexibility depending on the lender’s interpretation of Fannie Mae's guidelines and your property’s new appraised value.

Quote from @Travis Timmons: It's really tough and risky if you are just starting out.
