You have a number of issues in your post unfortunately.

She’s currently not paying rent, and while she has some health issues and no stable income, she’s been communicative and open to general talks, with a possible option to vacate through a cash-for-keys arrangement, though this might take around six weeks and some hard work.I plan to rehab the property and eventually rent it out, potentially to a Section 8 tenant.

Part of the scheme involved issuing “Accelerated Promissory Notes” offering a fixed 12% annual return over four years ( Link ).On page 8 of the SEC’s charging document, part of the scheme was issuing to investors “Accelerated Promissory Notes” that offered a fixed 12% annual return over four years ( Link ).That this is the same “Ron Fossum,” is clear from his included background search.

Will having money fix that issue?

Any repair issues the new acquisition has you will feel to much greater magnitude due to the property carrying a lot of debt.

The reason why, you're likely going to have issues with raising rents on your newly acquired tenants.
