Ive been listening to podcasts, reading a ton of books and practice running numbers on deals for the past 6 months.

@Ben SmithIt may be worth the expense to pay a CPA for the expertise in answering your questions.

Not my area of expertise but my understanding is that the winning bidder at the foreclosure auction is the owner subject to the 1st mortgage.this is probably subject to state law but generally the 1st has to accept you as the new borrower. 

These include CAP Rate, Cash on Cash, Debt Service Coverage, IRR, NPV and so on.Risk Matrix Risk matrix helps in assessing risks associated with real estate investment decisions.Identification of key risk factors Evaluation of potential risks Creation of mitigation strategiesEnvironmental, Social and Governance (ESG)ESG in Real Estate encourages responsible investments and sustainable practices.

Utility service billing may also need to be changed, if any are provided to the tenant such as water/sewer, gas, electric, (internet or cable tv for many condos).With regard to "transfer the lease agreement", there is no specific "form", but a written notification needs to be properly delivered or mailed to each tenant as I described in the first paragraph of my initial response to your post.It is "Best Practice" for any and ALL agreements, and most communications to be in writing with regards to Real Estate.

Networking is always a great practice and you never know who you might meet there and what good information they have to share.

If you turn the main breaker off so everything in the house is dead there is no need to check for live circuits (still good practice to check though). 

We had to remove or evict practically everyone (except the sec 8 tenant) shortly after acquisitions.

Nothing would be a deal breaker alone, but factor this level of expertise in when evaluating the complete picture.For example, a big problem that I've seen is if a single tenant building is applying with a regular lender, sometimes they apply a vacancy to their own DSCR (Debt Service Coverage Ratio), and they apply a vacancy factor for a single tenant building, which is just wildly inappropriate.
