Can Seller Financing Benefit the SELLER?

Options are to take out a loan for the 25% and just purchase or co-sign a multifamily or just co-sign on a SFH so they can get the 5% down, no loan needed, there wouldn't be any real benefit to me and my husband as we would be assuming the debt but we would be helping our kids out.

You're right, I should have said once a year or more....because one of the main benefits of the inspection is to have a professional on-the-record.

the benefits of long term rentals are... all of them together.

It’s always a good idea to consult with a tax advisor or real estate attorney who specializes in 1031 exchanges to ensure you're following all the rules and maximizing your tax benefits.

I am trying to evaluate the benefits & risks on purchasing a 2-4 family or a single-family home and convert/build an ADU.

Pros to my current position: Secure, w2, pay is above average, benefits are stellar, schedule is somewhat flexible (can leave if I need to without penalty; vacation when I want - utilizing banked time on both), 3 miles from home, and hopefully a pension in 17 years. 

Real estate should at a minimum get you 6% Cashflow + 8% appreciation  and 2-3% in mortgage paydown all based off a 25% down payment.Yes sir, those are all benefits not always talked about in the real estate investing world!  

You will see the savings if you hold the loan long term and do a cost benefit analysis.
