If so, taxes will accrue forever, but the property will never go to auction. 

They added "Appreciation" and "Equity Accrued" to the spreadsheet, that together bring up the number to 15%.

So essentially, the question is if paying that $26k in extra interest over the course of 7 years is worth having that extra ($3069-$1140)   $1929 a month for three years and if investing that $1929 a month would result in more than that extra $26,000 of interest I will be accruing for not putting it towards my loan.  

Our Dilemma Now that our savings is basically depleted and any emergency we may have health-wise could wipe that out and accrue debt for us (I'm uninsured), it has motivated me to make a change.  

We are looking at breaking even with all the loans we accrued on the property for floating it for a year.

On the contrary, you would be losing money if you kept that in your bank account or CD only making 2% while your loan is accruing at 3~6%. 

If you're ok having a bunch of debt and it doesn't scare you, then rack it up, but if you think you're going to have trouble sleeping at night because you're afraid of some sort if event that will leave you bankrupt all of the sudden, you should probably keep from accruing a ridiculous amount of debt.IMHO if your monthly cash flow is high enough to net a positive gain every month, consistently, without fear, your doing just fine.

If you come in as an investor or owner and intend to add value to the community and bring a property up to standards, they are are typically very forgiving with the fees that someone else accrued on the property Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

For me, I want to accrue wealth, so spreading my cash across multiple properties gets loan pay down and I increase my wealth courtesy of my tenants.

If it is, property taxes and mortgage interest are added to your itemized deduction and you would then compare it to the standard deduction and take the higher of the two.If you purchase in 2018, your mortgage interest/property taxes will cover the full 365 days and be higher.if you close on the property in Mid-january, your mortgage interest/property tax deductions will be lower as you will only have accrued it for 350 days.There is another thing to factor in is the property/state local tax deduction starting in 2018 is capped at $10,000.
