I have no choice but to commit to this game for the long-haul.

I think focusing on a BRRR (either SFH or MH) would be beneficial for your next deal.

Given the choice between cash now of say $500k, or REAL equity of $600k, I choose $600k equity as long as the $600k is greater on a RISK ADJUSTED BASIS.  

SFH can have more value add options and choice of area to buy.

I would be shocked if you evaluated this property honestly if it would be a high choice for a rental. 

Though not cheap, Perrysburg has seen consistent appreciation, making it a good bet for long-term growth.Investing $100K+ in Toledo:If you're putting $100K+ into one property, Ottawa Hills and Perrysburgwould be top choices for appreciation-focused investments.

Im 23 and will continue to work until 30-35, and by then I would be able to either continue working BY CHOICE rather by necessity.

If it is in a highly desirable STR area (the beaches, Riverside etc) it may be beneficial to sell it furnished.

Another choice is that you have the level of interest that should be expected at a 15% vacancy rate.  

Although rarely is it useful or beneficial to utilize (finance) that much additional principal and/or interest.
