From a commercial RE perspective, I would suggest looking for opportunities that are less risky in today's environment: industrial, mobile home parks, self storage. 

(The same could be said for self storage, mobile home parks, etc.) 

@Jessica Singh sorry to hear about your situation as you stated, I wish you well.There are tons of podcasts, books & blog articles to help you.First define your criteria and figure out what your lane is as far as single family, multifamily, self storage, mobile home parks or any other real estate vehicle such as hotels and commercial real estate.Once you narrow it down your search for learning information will be easier for you as you continue on your journey.Happy investing!

Just some water damage and loss of items in the storage room and landscape rearrangement.   

what will be a reasonable price to buy  a warehouse around 10k storage and 1k office space in that area?

Also, I'll do fresh paint and flooring.

Inherited tenants then start "fresh" with their security deposit, with me. 

It has 1600sq feet of commercial space, 1,000sq feet of dry storage space in the basement, and two two bedroom apartments above the commercial space.

It was sold for $25,000 4 months ago and completely rehabbed: new metal roof, new appliances, new cabinets, new counter tops, new flooring, new carpet, fresh paint.

Was on another post and the question was asked, "What is a good COC for B and C self storage."
