Yes, you can use part of your Traditional IRA funds for a down payment on a home through the First-Time Homebuyer Exception, which allows you to withdraw up to $10,000 without incurring the 10% early withdrawal penalty.

When a loss was incurred I accepted it as a cost of investing without thorough investigation and or the percentage probability of an unprofitable outcome.  

Here's the deal: You don't need to withdraw and return the current security deposit just to collect the additional $100.

@Tinia James Yes, you should still file taxes even if you made no profit, especially if you incurred any business expenses.

Is there a way to access the additional features without creating a new Stessa account through the BiggerPockets link? 

If they're great tenants and you want to keep them, I would consider covering the invoice and having your PM realign expectations so you don't incur more expenses in the future.

Incurring debt before you have sufficient earnings to support that debt.

I do not see that home prices have dropped 2-3% and this is a lot of added savings in additional to a downpayment if so. 

Duplex have different zoning that may permit additional units.

Additionally, are there any other factors I should be considering when purchasing a duplex or triplex?
