However, this recommendation could change based on specific interest rates, your personal financial situation, and long-term goals.

If you don't have any leads or don't know where to start here are a couple suggestions: ask brokers who people use for debt, find a mortgage broker as they have access to different buckets of capital, use a website like CoStar to look at closed transaction over the last 12 months and see who they used for debt.

In real estate (and life), the "under promise and over deliver" principle is crucial for building trust and fostering long-term relationships.

My current primary ( scenario 1) Keep the primary for the life of the loan ( current rate is 4.5 so i dont see my self refinancing anytime soon)current home value 1,150,000Loan amount 935,000appreciation estimate 5% per year after a 28 year hold and the house is paid off I would have a house worth 4,312,000$my current mortgage is 6125$ ( piti) included My second option( scenario 2) Sell the house, walk away with $150 ,000 ish in hand and put that into a low cost index fund Rent a house elsewhere for about 3000$ ish and take the extra 3000$ im saving everymonths from not having to pay my mortgage and puting that money in the index fund as well I ran the numbers on both of these scenarios and doing what I mentioned above would break even at about 28 years meaning my stock account would be worth 4.3 million just like my house would , but the only is that holding a house for 28 year would mean 28 years of property taxes, loan interest ,home insurance and repairs etc whick I calculated to be about 1,200,000$ at minimum which raised my eyebrows to say the least Also i understand that each of these options ( stock market vs real estate ) will have there tax consequences ( long term capital gains) so any thoughts on that would be appreciated as well.

I understand that the Section 121 Exclusion for Primary Residence allows you to sell your Primary residence and not have to pay ANY capital gains taxes on the gains/proceeds - as long as you use those funds to purchase your next Primary residence.What I cannot seem to find the answer to is - what is the maximum timeline allowed from Sale of the first Primary to Purchase of the replacement Primary residence? 

Darrell,I ran into a similar situation last year. 

I would also recommend doing a balloon payment sometime from 2-5 years of executing the deal so you don't have the service the loan for a long time.
