Cutting down on gov't spending and the pulling jobs back into the US should help offset some of the tariffs, but it will come down to which items exactly do get tariffs put on them and to what degree the tariffs are (10%/20%/50%).Overall, my guess is that rates will go down for early next year, rise during the middle quarter-third of the year, then fall slowly afterwards.

well 70% of 455ks isnt much more than you currently owe at 283k the 70% of 455k is 318.5k and after closing items you might only net 20-30k tops (new loan minus current 283k - closing items = net proceeds in "hand.").So The question you should be thinking about is what are my closing items and is this enough cash to accomplish my mission/goal?

I have one in NE FLorida, he used to own 300 doors, I call him and run my deals by him, I am hoping to get smarter about deals and have him point out items to me SO THAT he can manage them for me, he manages 20 doors now instead of owning.

Set Aside for Major Repairs: Most Cap Ex items have a life expectancy.
