To sum up, knowing what is needed for a loan, following local laws, and placing emphasis on being honest and transparent are crucial aspects in real estate deals.Good luck!

Investors tend to be more discerning and astute, meaning they'll closely scrutinize every aspect of the deal. 

Underestimating the time commitment necessary for successFunny how the more complicated, higher risk, and more knowledge required to succeed in a Particular aspect of real estate the easier and simpler the gurus make it sound.

Are there any specific calculators or tools you recommend for analyzing the financial aspects of a seller financing deal?

@Daniel Kauffman for one, I didn't like the lack of control over my own rental and it took the personal aspect away. 

Take into account aspects such as affordability, cash flow, savings, market trends, and long-term goals.

Yes I am starting out so this is why I don't see the need for a CRM especially if I plan to work with a PM to handle all aspects of the rental .. which a CRM wouldn't really "track" 

Multifamily DSCR Loans, or DSCR Loans for 5-10 unit properties, combine the best aspects of DSCR Loans (30-year fixed rate, easier qualification and underwrite, low down payments) for properties that traditionally were ineligible for that type of financing.

Some sellers haven't filled tax's since Gerald Ford was president, other do it via receipts in a shoe box, some just make up numbers, some have an accountant, it's literally all over the board as is every aspect of small MFH investments, the only standard is there is no standard. 

Mental clarity has been the biggest gain for me throughout this journey and it has helped me in every aspect of life.
