Estimating repair costs off MLS pictures...okay to do? Or stupid?

[Kingsley Okwerekwu]

How can I estimate rental costs on a MLS listing from my computer?

I am looking to begin my first flip in the next 2/3 months...is it okay to see fixer upper appear in my market and just make an offer of what I “think” the numbers would be? This “estimated repair cost” is the toughest part about “doing the numbers” for me.

Are there certain major expenses (roof, heating etc.) that may be hidden from the pictures and the mls listing? Or will all agents have to disclose that information, for a fear of not disclosing a defect?

Would a better option be to make an offer and then ask a certain list of questions that may not be disclosed? Or should everything I need to know already be disclosed on the listing?

I have this super huge fear of buying something that I thought was good, finding out it will cost WAY more, and then my parents and everyone around me calling me a massive failure.

Thanks!
