If you sell a property, and do a 1031 exchange with the proceeds, but don't need all the proceeds for the down payment of the next property, are you taxed on the additional profit that isn't part of the exchange?

The front end can sometimes be tedious to get approved by the local housing authority, but rent payments are always timely.

With 5% down payments and all the expenses deducted, there seem to have close negative/only around $100 cash flow each month.

The tenant hasn’t been the greatest: late payment with not always paying late fees, multiple complaints from the neighbors, changing phone numbers, ect .

Put in your down payment and terms  in the calculator. 

-Allocate a portion of your funds toward extra payments on the current mortgage while also setting aside money for a new investment.

I've been able to afford my payments so far without much issue.

Did you have an agreement in writing signed by both you and the designer regarding payment schedule and purchases?

Just curious - what sort of down payment do you usually require of US citizens? 

Quote from @John Davey: Id appreciate any help, as ex. if i take out say 100k home equity loan and use 50k each as down payments/cloing costs my understanding is i cant deduct the interest?
