2.Are there strategies to reduce the required down payment or secure better mortgage terms?

., mortgage interest, taxes, repairs, depreciation) on Schedule E starting when the property is placed in service.

If you are doing rentals, especially long term rentals, you are unlikely to be able to live off of those for a while if they have mortgages. 

. - Taxes are on the higher side at $6,000 yearMy Numbers: $115,000 putting 20% of my money $23,000 and finance the rest with total expense of $1,834Monthly expense numbers: Future Maintenance 13% $273 - Vacancy 5% $105 - Property Insurance 5% $105 - Property Taxes 23% $500 - Property management 10% $215 - Office/Travel/Legal 4% $84 - Mortgage 26% $552 - Monthly Cash Flow - $316 per month or $3,792 per year so Cash on Cash = 17%I think this looks like it is a deal worth doing and I also believe I can bump the total rent up by $50 each tenant which I think make it even better.

I own a mortgage company now that does both residential and commercial finance, but I spent years as a commercial banker with both big banks (First Union/Wachovia) and 2 community banks.

Quote from @Shawn Questa: Hi all,I am curious what some of the Pros would do to Help a Seller in this situation while making a Deal happen.I found a 200+ day old MLS Listing where the Agent said the Seller is in Financial Ruin, hasn't Paid the Mortgage in a year, owes about 180k on an approx. 210k House and multiple Buyers have backed out.I don't know how someone could not Pay their Note in a year and not at least be in Pre-foreclosure. 

Consequently, it’s up to these companies themselves, not demand from investors, to set the value of their shares.Non-traded REITs own about 10% of the $2.5 trillion in real estate assets held by REITs, not counting private ones whose shares are only available to accredited investors, according to the National Association of Real Estate Investment Trusts, a trade group.The SEC and the Financial Industry Regulatory Authority, a self-regulatory organization for brokerage firms and exchange markets, issued investor notices in the mid-2010s that warned of potential risks from non-traded REITs.They include a lack of clarity as to how shares are valued, difficulties in selling shares readily, high fees often paid to managers with possible conflicts of interest, and the potential that investor cash and loan proceeds can be used to pay dividends during unprofitable periods.More recently, high-profile investment firms such as Blackstone Group and Starwood Capital Group have started their own non-traded property trusts with offers to disclose more information, charge fewer fees, and allow shares to be cashed in more frequently.

I have a private investor who will lend his own capital for ADU financing.

The seller also has a mortgage on the property.

Very unlikely unless you find a private lender/individual to do this as a one-off.
