Sell or Hold? Condo almost paid off.

[Red Peterson]

have a 3BR, 3ba partially fin basement almost paid off. Ready to purchase a new home.. i feel if I sell, I’ll get a good equity but I also feel that in the long run, its best to hold. I feel like the real math in my equation is not the price tag i paid but that and all the interest i paid in 12ys so im not sold to just sell the property… hold and get another loan for higher balance and rent out current condo or sell current condo so my loan principal will be lower? If i rent it out, i’ll need to spend 10k to update necessary things.. what woukd you recommend? Noob here…
