When factoring in additional costs such as maintenance, property management fees (if you do not opt for a property manager, and you should), and potential vacancy periods, the financial burden could increase.Check this out: If you're breaking even on rent at $1,600, any additional expenses or vacancies directly impact your pocket and mental health.

Yes that can be an option but at the moment right now i have a deal in the works where i would need more then 50K to be able to make the numbers work I also recently went to a random bank and got a LOC for up to 50k at 11.5% interest rate with no fees.

Then you would have realtor fees and closing costs.

If so, do you know a way to avoid the high cash advance fees/rates? 

We fee it’s fair.

I have an 8-5 that brings in just under 100k and I work as a part time realtor(sold 3 houses last year and had a rental deal too) and I bartend most Sat nights(300 a night, working 4-11)If I sell the 2 family, after 15% cap gains and 2% to the buyer agent and lawyer fee and pay off all our debt(wife and myself, not mortgages) We would have about 150k left over.If I sell the cabin, after agent fees and cap gains we’ll probably walk with 60k.Would keep pushing forward?

Add costs for lawyer and court fees. 

To do anything like a refi you would pay all of their fees again and start a new loan at 15% - 20%. 

Ask for a breakdown of fees and an explanation why the interest rate increased.

Just to keep your license you will pay several thousand dollars per year in fees for your brokerage and MLS and Supra E Key, etc.
