Just another quick question, Because I was unaware of the situation before going under contract, do you think now knowing this a $10-15k reduction wouldn’t be out of the question of asking?  

If it takes you multiple years to save up money to invest those are valuable years lost of cash flow, tax benefits/depreciation, appreciation & debt reduction by the tenant paying the loan down.

Buy all 8 of those properties as fast as you can and then focus on debt reduction after that. 

This is a much, much better plan than moving overseas and never coming home (did someone up in the thread earlier actually suggest that or am I taking crazy pills?).

(See note above about earlier extra payments being worth more when trying to figure out why which payments go to which same rate loans saves you more or less money.)On the Contrary, Infinite banking is a concept using permanent life insurance the concept mentioned in this post is about velocity banking, mortgage debt acceleration, and a few other names that involves taking idle funds that would typically be parked in a checking/savings and using it to accelerate debt payoff and interest reduction.

When a payment is received half of the amortized principal goes to your principal reduction or your cash paid out as the return to capital, the rest is profit and it is treated as interest on your investment.

Everyone wants the magic pill.

In some seller's market, this is harder to do and might be less. however, in a buyer's market i would start with a 15% reduction...after a counteroffer, you know that the seller is willing to talk more on price rather than just rejecting your offer period.

But paying anything in the scenario you described would be a tough pill to swallow for me personally. 

There's no point in agreeing to $100 reduction and then finding out you don't even meet my qualification standards.Show them you're worth the effort first, then negotiate.
