Sounds like you get her portion of the rent for the next five months and then work with him for the remaining balance each month.

I want to strike the right balance between transparency and professionalism.Appreciate the guidance—thanks again!

When we tell them our opening bid is $1.5M they try and negotiate off the $500k because that was the original loan balance but due to other circumstances like modifications etc. the loan balance has increased significantly. 

To get to the ARV of $250,000 , I am assuming as follow:Because you spent $15,000 in renovation, I am assuming you increased the Initial value of the property at 30,000 bringing it at $230,000Add a 8.69% home appreciation for one year $20,000Estimated Home Value After 1 Year:$250,000Refinancing Breakdown:New Home Value (Post-Appreciation): $250,000 New Mortgage Amount (80% LTV): $200,000 Existing Mortgage Balance after 12 months: -$158,035 Assuming 3 Months Interest Penalty for Breaking Existing Mortgage: - $2371Total Cash Pulled Out: $39,594, allowing you to recover to pay a portion of your initial investment of $63,548, leaving $ $24,015 in the deal.Many new investors mistakenly believe the BRRRR strategy ends after the cash-out.

I would look for a bunch of Sub To Deals with 2-3% interest rates ...... then rent out for cash flow and huge equity build up when rates are really low (check out amortization schedules and compare 2-3% vs 6-7% with the same balance and length of time - check out the principal portion each month - the lower the rate the higher amount goes to principal PLUS better cash flow).

My idea to buy a home is to get an 80% LTV 1st mortgage from a bank, take over that mortgage and give the seller a second mortgage for 50% of the 1st mortgage balance because I need some cash to cover the payments, which the amount of cash would be more than the remaining equity in the home.

Consider self-directed IRAs and connect with working parents for a balanced real estate and family strategy.Good luck!

At no point does there appear to be an accumulated balance but rather just a series of payments coming.

That said, the right team on your side can make the permitting process and inspections far less painful.I’m curious... as you refine your plans, how do you see yourself balancing the home’s original character with these modern upgrades, and which element of the design do you think will win over the pickiest buyers? 

Yes it’s common to have an additional guarantor who has a balance sheet added as a credit enhancement.
