Furthermore, as we all know the first few years of mortgage payments are mostly all interest expense and less principal, so my outstanding balance on the debt is remaining roughly the same.

I'm a man of principal.

Core principals have not changed - Buy low, sell high. 

I am trying to figure out what the best thing to do for a friend is in the situation outlined below:Home Value $570kowed 1st mort $496k (current loan was modified and principal reduction completed for $100k reallocated in form of balloon payment at end of loan term)no 2ndarrears $30kIn process of going through bankruptcy, however, want to complete a lease with option to buy. 

If I start seeing huge losses of principal, then I move on.

Here's a summary of the economics.They purchased the property for $280,000 in 2004.The loan balance is about $178k.Monthly principal and interest payment is about $1,265 with $709 currently going to interestProperty taxes are $4,116 annually and insurance is $1,000.Currently the house is vacant for the sale so there's no rental income.Therefore, the monthly burn is -$1,135 (ouch).For the sale:Property was originally listed at $335k and they received 0 offers at that price. 

My guess is that business pays you and you then pay the principal and interest on your line of credit.LLC will cut the check to you and mark it against Interest Exp.This will look like this on your LLC's books:Debit Interest ExpenseCredit CashAs for everything, have a promissory note to make it official.

Currently I'm amortizing 750$/month of principal, which will grow over time.I have two other rental properties with positive cashflow of 200$ each.What considerations should I take when checking if I want to prepay the mortgage on my negative cash flow property?

@Nick McBrideFirst you have to determine what is your responsibilities of paying and what is the tenants responsibilities of paying.As a general rule - the landlord's expenses/allowance will include repairs/capital expenditures/vacancy/property taxes/mortgage interest/mortgage principal/etcDepending on the county - Water and Sewer can be included in property taxes and be the responsibility of the landlord.Items such as electricity/water/gas is up for negotiation to be paid by either the landlord or tenant depending on what is said in the lease.
