This property is gonna cash flow over $1000 a month after we're all said and done with utilities mortgage and more.

It's not quite as easy as renting out two sides of a duplex, but with the right marketing and management you could rent out the extra unit to supplement the mortgage payment. 

The buyer may pay off the remaining balance at any time without penalty.2.Late Payment Penalty: A late payment fee of 5% of the overdue amount will apply if payments are more than 10 days late.3.Loan Security: The property will serve as collateral for the seller-financed loan.A 24 month balloon payment is a deal killer.Put your numbers in front of a mortgage broker and see if they will even do the deal.

Have you ever taken out a loan to afford the down payment for a mortgage and do you know of any lenders that offer that?

That's because the city won't calculate the actual amount till a structure is built, aka it's not just a plot of land anymore.This will obvious cause your property tax bill to go up and also your mortgage escrow account as well (sometimes these things can make your mortgage shoot up a few hundred a month). 

My mortgage brokers but I’m not ready to reveal them just yet.

Such luxury as indoor/outdoor pool, park for skateboard, tennis court, tiki bar with dance floor… of course if you need to think about the ROI and how much maintenance it takesBest ROI items are - big screen TV, hot tub, playground, PS5, BBQ…The issue is cheaper items require more maintenance.

I'm an investor and mortgage broker and have options for loans that go as low as $75,000 and down payments as low as 15%, which makes it easier to stay above $75,000.

Quote from @Brendan Jones: I am very new to learning about real estate and am looking for advice on my first home and how I can best use it to help offset my mortgage and generate cash flow.

You will likely need to find a property that will cover most of your mortgage payment, but not all of it.
