First purchase! How can I be sure I'm making the right choice?

[Hannah Joy]

Hi all! With rates low but purchase prices high, and uncertainty in the air, I've had an offer accepted. It is my first attempt to get my foot in the door with buy and hold real estate and I'm not gonna lie I'm scared! 3bed 2bath with a small office/potential 4th bedroom and a detached garage I'm hoping to convert to an adu. Double lot with huge backyard and room to build in the future. It is 299k where most everything else like it in the area is 350k, seller credit of 9k. I plan to ask the seller to complete the repairs in the pest report and the home inspection (estimates around 10k), and I'll take care of the remodeling and get it up to rentability...likely 10k there as well. What question should I be asking to make sure this is indeed a good deal? Thanks!
