Are there any red flags I should watch out for when dealing with buyers who propose alternative arrangements like this?

Alternatively, can you use either unit as an STR to increase cash flow even further?

The program was created to give low-income tenants an alternative to living in federal project housing.S8 sets their rental rates to the LOW-END of market averages, if not slightly below.

Over time, I’ve accumulated more cash reserves and don’t need as much flexibility, but I’m actually in the middle of a refinance right now using an interest-only mortgage—because the pricing with the lender and the corresponding ARM is more favorable than a comparable principal-and-interest loan.The key with these alternative or "exotic" mortgage types is that you need to be financially savvy and have a solid plan.

The alternative is to set up a self-directed IRA, or better, a truly self-directed Solo 401k plan, invest in alternative assets, and then do the conversion.

Does anybody have any advice on alternatives to resolve or get this fixed before I go all out & call a plumber.

Alternatively, you might want to travel to Mexico and check for yourself on the ground.

That's not exactly a good alternative to sub to. 

Interest rates are going to have to come down because there's no way the federal government can afford long-term interest payments at these higher levels, and other countries are going to buy our debt even if their return sucks because there's no realistic viable alternative.

However, there are lenders who offer more flexible terms or even no prepayment penalties, depending on the deal structure and your investment strategy.To find such lenders, here are some options to consider:No Prepayment Penalty Loans: Some lenders, often private or portfolio-based, offer DSCR loans without prepayment penalties, though the trade-off might be a slightly higher interest rate or fees.Yield Maintenance or Defeasance Alternatives: Ask about other prepayment structures like yield maintenance, which can sometimes be less restrictive depending on market conditions.Custom Terms: There are lenders (like us at Phoenix Funded) who can structure loans tailored to your needs.
