@Diandra Duncan My first property I purchased was a condo in Kew Garden Hills, Queens. Although that transaction does make sense to me today after I learned to invest long distance. It was a great way for me to get started while living in NYC. I house hacked it by renting out the extra bedroom. It helped me in many ways—building equity instead of paying rent, getting experience as a landlord, years later was able to cash out refi the equity, and even 1031 exchanged it two replacement properties.
But in my opinion, with this being your first purchase and the fact that you said it is old, I don’t think you should waive inspection and possibly not go the route of doing an informational inspection, unless you walked through the place with an expert like a contractor. The times I done informational inspection was when I had more experience in spotting things and did some research to give me confidence there weren’t major issues (e.g. an apartment being converted to condo in the last couple years so it had meet some requirements recently; all the major items like plumbing, electrical, HVAC were replaced recently).
It sounds like the seller is allowing an informational inspection and not willing to fix or provide credits for anything found to be wrong, but make sure you get clarification. Waiving inspection is completely different.
I never waived mortgage contingency completely. But I have agreed to cover up to $20k of difference if appraisal was below purchase price. It did help me win the deal. I was lucky that appraisal actually came in above and I had the extra cash just in case if I needed it. But since you only have enough to do 5% down, it doesn’t seem like this is an option for you.
