The home is worth $1.3mm today, and I have $700k remaining mortgage and $600k equity in the house.

Condos and Townhouses remained at normal levels in comparison to other years.

Cash-on-cash return for this home is 20.50% and the estimated time to recover original cash invested will be4.88 years if rent remains the same and no major expenses occur.

Option 1:Pros:Simplicity: You avoid the potential complications of alerting the lender.Maintains Low-Interest Rate: Since your loan is at 3%, you continue benefiting from this favorable rate.Avoids Immediate Full Payment: You won’t be forced to come up with $45k immediately.Cons:Risk of Detection: If the lender identifies the payments coming from an LLC, they might call the loan due.Potential Consequences: If the lender enforces the due on sale clause, you might be forced to pay the remaining loan balance quickly.Option 2:Pros:Transparency: Being upfront might build trust with the lender.Possible Flexibility: Given your solid payment history, the lender might agree to the arrangement.Legal Compliance: You avoid any potential issues with violating the terms of your mortgage agreement.Cons:Risk of Loan Acceleration: The lender could still decide to call the loan due, forcing you to pay the remaining balance.Potential for Higher Payments: If forced to refinance, you might end up with a higher interest rate.Given the pros and cons of each option, but a cautious approach might be best:Consult a Real Estate Attorney: This can give you a clear understanding of your legal standing and potential risks.Evaluate the Importance of the 3% Rate: Weigh the benefits of keeping your low-interest rate against the risks of potentially having to pay off the loan early.Consider a Gradual Transition: This method allows you to continue benefiting from the low-interest rate while reducing the risk of triggering the due on sale clause.

@Cameron Daste- thanks ....you will have a challenge with finding much in the KING COUNTY area for  500-700K range ...if you want to remain local - you will likely need to broaden to Pierce / Snoh  County area .   

Here are some options and considerations:Loan Against Equity/ETFs:Margin Loans:Description: Margin loans allow you to borrow money using your investments (such as stocks or ETFs) as collateral.Pros:You retain ownership of your investments.Generally quick access to funds.Interest rates can be relatively low compared to other types of loans.Cons:Your investments are used as collateral, so if their value declines significantly, you may face a margin call (requiring additional funds or securities).Interest rates can vary and may be higher than traditional loans depending on the lender and your creditworthiness.Securities-Based Line of Credit (SBLOC):Description: Similar to margin loans, SBLOCs use your securities (stocks, ETFs) as collateral, but they typically provide more flexibility and may not trigger margin calls as easily.Pros:Allows for ongoing access to funds as long as your collateral remains sufficient.Interest rates may be competitive.Cons:Similar risks of potential margin calls if the value of your securities drops significantly.Terms and interest rates can vary widely among lenders.Comparison with 401(k) Loans:401(k) Loans:Description: Borrowing from your 401(k) allows you to access funds without selling investments, using your retirement savings as collateral.Pros:Typically low interest rates.No credit check required.Interest paid on the loan goes back into your 401(k) account.Cons:Usually capped at a percentage of your vested balance (commonly up to 50% or $50,000).If you leave your job, the loan may need to be repaid immediately or could be considered a taxable distribution.Potential opportunity cost of missing out on market gains if funds are withdrawn from investments.Other Alternatives:Home Equity Line of Credit (HELOC):Description: If you own a home with equity, a HELOC allows you to borrow against that equity at typically lower interest rates than unsecured loans.Pros:Lower interest rates compared to other types of loans.Interest may be tax-deductible if used for home improvements (consult a tax advisor).Cons:Your home serves as collateral, so failure to repay could result in foreclosure.Personal Loans:Description: Unsecured personal loans can be used for various purposes, including investing, but typically have higher interest rates than loans secured by collateral.Pros:No collateral required.Funds can be used for any purpose.Cons:Higher interest rates and stricter eligibility criteria based on creditworthiness.I am a loan officer and we do some of the loans stated above.

However, for personal reasons the tenant is no longer interested in remaining in this rental and wants to be "bought-out" of their "ownership".First and foremost, a verbal agreement just isn't going to cut it and getting a signed legal contract is the first step.

Even though I'm building an ADU, it's still remains on the same parcel as my primary home.

I guess I'll see if I made a good deal or not in order for this to work.Blanca,Yes, you could take a HELOC for the remaining repairs, or refinance into a bridge loan and get some capital back to make those repairs, and then refinance into the long term loan that you are looking for. 

If it doesn’t meet that criteria, it would just be treated as an early termination request, with whatever penalty is in the lease, and both would have to agree or remain responsible through lease term.
