It's possible underwriters see this and shut it down right away.We have many current clients who have this blended model, but they are local to their properties.  

-I would like a good blend of cash flow & appreciation, but need more cash flow in current circumstances. 

Buying a tract house and putting in the basic LVP, white shaker, subway tile, greige walls will blend in with most other listings.  

This would give the investors a blended 12% annualized return, with the GP keeping 100% of the profit above that. 

But, these are set up as a blend of one-bed suites and efficiency suites.

If your first is 2.75% 30 year and large it's a great blend. 

That would go in the face of an often referenced study the appraisal institute conducted by tracking actual sales data from which they calculated that homes with solar sell for an average premium of $15k. https://www.nytimes.com/2015/02/22/realestate/sola...Think about it: assuming house A and house B are identical other than one has solar and one does not (and you can't even see the solar because the panels are black and blend in to the roof), if house A has $2k/yr. electric bill, and house B has $0/yr. electric bill plus earns the owner $200/yr. selling SREC's back to the utility, you're telling me you'd pick house A?

When you calculate the blended rate between the low first rate and HELOC versus the 30 year refinance in most cases the refinance makes more sense.If you live in this home but rent the basement there should not be an issue with the lender or bank. 

A second position mortgage (so a loan that takes the backseat to your existing mortgage) will have a higher rate than a first position, but with a rate as low at yours, your blended rate between the two will still likely be lower than if you were to refinance.

Get breakfast blend (light roast) and get a dark roast as well.
