I’m super excited to get started and for reference, I’m debating between using the BRRR method or fix and flip strategy to start my real estate investing.

It looks like there's no plumbing apart from in the kitchen area, which is used in the second floor bathrooms as well. 

My investment idea/plan is to buy a single family residence (BRRRR method) to either flipp, rent or airbnb, but i would love to hear from ppl who have lived in a townhouse and have done this. 

Tokenization can be used for 1) The tokenization of Real Estate Investment Trusts 2) timeshares 3) Real estate ownership using an SPV 4) Investing in new projects 5) Loans for developing projects and 6) shares in real-estate funds.Many types of real estate can utilize tokenization including office buildings, retail spaces, single-family homes, and multifamily structures.What are the advantages of tokenization over traditional methods of real estate investing?

You have when the contract was opened and you have some dated method of when the seller told you the tenant was behind.
