Could you upgrade the property to improve rents / reduce maintenance / reduce vacancies / and even enhance equity during your hold period?

I agree with the previous responses, your best bet is to purchase a home that does qualify for traditional financing, there are down payment assistance programs available that can help enhance your 10%. 

I realize I could always make a lower offer to enhance the returns.

As much as you can outsource activities, there are many decisions which will either enhance or destroy the returns.

This does not enhance my experience on BP.Communicate.  

I think however, you should get a Masters degree on a technical subject that will help you enhance your career.

In real life, investors often refinance multiple times not only to optimize their returns and pull out more equity but also to potentially secure better interest rates.Benefits:Realistic Scenario: Investors often refinance multiple times to maximize their cash flow and equity, and this feature would allow for more accurate financial planning.Comprehensive Analysis: Having the ability to input multiple refinancing stages would provide a more detailed and accurate picture of long-term ROI and cash flow.Interest Rate Optimization: With improved interest rate tracking, users can make informed decisions about when to refinance and potentially secure better rates, further enhancing their returns.Time Savings: It would save time for users who currently have to manually adjust calculations outside the calculator and compile results.PDF Integration: The ability to generate PDF reports with these refinancing stages included would be a game-changer for presenting investment proposals to partners, lenders, and other stakeholders.I believe that adding these features would significantly enhance the functionality of the BiggerPockets BRRRR calculator and make it an even more valuable resource for the community.

It enhances it...much faster. 

Your ability to manage rental properties successfully can enhance your profile and potentially lead to more favorable terms.

A great enhancement to the request.
