Some vps services block 25 as well but it is usually configurable. The monthly cost of a vps is a few coffees and you get much more robust hardware and environmental conditions for your server and much better management tools. I did the home server thing well over a decade ago with a commodity pc sitting on a small ups. The main concern was leaving it running unattended when away from the house for any time. Especially during summer heatwaves. I found it wasn't a sustainable solution if you do any amount of travelling away from home.
