fear of extended vacancies want to buy first property

[Travis Lackie]

hello, i am really interested in buying my first rental property, and i want to start off with something small around 60-80k. i would like to convince my dad to co-sign it with me, but he has fear of not being able to rent it out. assuming i priced it alright or slightly under value, what are the odds of my property (assuming in a decent area) goes vacant for a super long period  of time?.. he is also very worried because of everything going on with a pandemic, but he has fear that if i buy it it will just not rent out but i tell him it's not true, what is the truth surrounding this field?
