Get insurance lined up well before closing so now would be a good time.You need a landlord policy, slightly different (and usually cheaper) than a normal homeowners policy.I have been super happy with USAA for our rentals - if you or your parents served then you can get USAA, they are set up to work with landlords.

If it does then you either get your own survey and hope it shows something different, comply with the neighbor's request or negotiate a settlement, say an easement to you for the encroachment.

Tax implications also differ; selling may incur capital gains tax, while rental income is taxable but offset by deductions.There are several factors to consider when deciding if you should sell or keep your property as a rental. 

Mind you, this was 2019-2021 so definitely a different environment for investing but the area is wonderful.

Would likely be breakeven at BEST - however as Alex said above if you can find one that lets you self rent that could make a difference.$22k net on $190k investment = 11.5% CoCR, which is good but you can achieve higher

We are getting conflicting opinions from different CPAs.
