I'd plan to pay off both loans within 5-7 years with cash flow from the rental and other income and assets.I'm an accredited investor and will still have more than a year of expenses covered in liquid assets and additional funds to buy another 1-2 properties in the next 2 years, which is my goal.I don't know if I've provided enough or the right information to get some opinions if what I'm planning to do with my current house and new home purchase makes sense. 

Hi Zak-Great question.It sounds like your credit union is offering you a Home Equity Line of Credit as they do not expect principal payments and your primary bank is offering you a Home Equity Loan.Personally, I don't like having to pay on an equity loan unless I use some of it and only pay on the part I use.Although, this is a personal decision for you.If you make investments that provide enough cashflow to pay the principal and interest to your primary bank on the equity loan it doesn't really matter to you as others are paying it.Another consideration is the amount of dry powder available to invest.

I provided evidence in my reply to no avail and the city wants to go forward with my hearing.

If you are buying the second lien the seller should provide you with a credit report which then you have the lender and account info from credit report so you could call to get the balance.

Can you provide 2019 and/or 2020 YTD income information?

Do manufactured/mobile home dealers provide seller financing option to buyers? 

Remote workers, people moving to a city but don't know where they want to settle more permanently, divorcing people who need a temporary stay, etc, etc.

Although when doing this in 08 to 2011  I was afraid to even look..And my banks had me on a very short leash I had to provide financial every 90 days if I wanted to keep my large lines of credit.
