A few things to consider from your list: Copies of the rental agreements ought to be attached as a requirement via addendum in the original purchase agreement.

You will probably be required to tear the entire floor out and out in a vapor seal.  

No activity though.A lot of people tell me that I should obtain my Real estate license to convert our rentals from passive to active income, but I don't exactly understand how that will help.I'm not looking to be an active real estate agent, but was thinking of obtaining my license to become an associate agent to fulfill the hour requirements and just for fun.Is this the right path?

The number usually varies from 10-20% depending on credit score, property analysis, etc.Some lenders will work with any level of investor experience, credit scores as low as 660 and can close in as little as 10 days (there are loan options for 640-660 credit scores- they require 20% down).Another good thing is interest only and 6-24 month loan terms- you can refinance by selling or refinancing to a long term DSCR rental property loan at any time once you complete the rehab.Once the property is ready you can sell it or if you want to keep the property as a long term investment, you can underwrite the loan based on your income /debt to income (DTI) ratios or you can go the DSCR route where the loan is underwritten based on the actual or market rents from the appraisal.DSCR loans won't use your income to underwrite the loan.DSCR loans are based off of down payment, credit score and either actual or market rents so it helps to supercharge an investor's real estate goals and net worth.Here's a bit more in detail about how rates are calculated for DSCR loans:1.

Admittedly, finding direct comparables has been challenging due to the unique nature of our family's home, but these figures give us a good starting point.I've taken the proactive step of having a property manager conduct an inspection, and preliminary feedback suggests that the renovations required might be relatively minor, pending the final review from the contractor.

The renovator mentioned the house is in poor condition, requiring a ground-up renovation, which would demand additional funding.I’d greatly appreciate your insights and advice on this matter.

Does this number require you to sell more to achieve a split which is more favorable to you vs them?

Whether they have a problem or not, building in an area like that requires some different considerations.  

When they refinance, they will still owe the original principal balance.
