Inspection watchouts on my first As-Is SFH, 1930 construction

[Suvir B.]

I am new to rehabbing, and in the process of closing my first purchase in Scottdale, GA. It's a For-Sale-By-Owner, As-Is purchase for a 2 BR, 1 Bath constructed in 1930. While I was able to purchase at a reasonable price, I want to be sure I am not blindsided by major issues which could kill the margin. I have 2 weeks for completing inspection, and would appreciate guidance on areas to watch out for.

I already noticed that the floor is creaking in a couple of rooms, there is no insulation, and there might be lead paint. Besides calling a general inspector to check for obvious issues, and a general contractor for estimating rehab costs, is there anything else I can do to reduce exposure?
