In my area, if landlord does not provide the itemized statement within proper time frame, the tenant has right to their full security deposit back, even if they caused damages, so I would make sure I followed proper procedure to protect myself.  

The timeframe depends on the deal struck between both parties and the seller's goals. 

As a lender in 1st position, I look for the following:  Purchase Price, Rehab Estimate (and how funded), Time Frame to Flip, and ARV expected. 

Most are like this: •Rates: 9% to 13% (Most Deals are 11-12%)Terms: up to 36 Months (Most Deals are 6-12 months)Fees: 2-4 points(%) of loan amount paid at closing (Most Deals are 3 points(%))Minimum Loan Amount: $50,000 (For loans less than $250,000 $2,500 minimum fee)Max Loan: 65%-70% of After Repair Value(ARV) 100% Rehab Financing Available (Require 20% of purchase price down payment or cross-collateral)Closing Timeframe: 48 Hours - 3 Weeks (Most Deals are 2 Weeks)NO PRIMARY RESIDENCES, NON-OWNER OCCUPIED ONLY, BUSINESS AND COMMERCIAL USE ONLY.

I think most of his flips are in inexpensive cities like Cleveland, Detroit area, etc. https://flipsystem.com/faq/I think $10,000 to $20,000 (before IRS taxes) is a really small profit margin.

I like as much data as possible, Chris brought up great info, I run my own also; like for like sq ft bed/bath count, close radius, only closed sales in tight time frame, not separated by busy surface streets, pole line open space etc.

Not sure the size etc, Also make sure to stipulate a timeframe as solar would take years to negotiate - do not be shocked if the seller wants a non refundable depositThis is very common in these types of transactions.

Most work like this: •Rates: 9% to 13% (Most Deals are 11-12%)Terms: up to 36 Months (Most Deals are 6-12 months)Fees: 2-4 points(%) of loan amount paid at closing (Most Deals are 3 points(%))Minimum Loan Amount: $50,000 (For loans less than $250,000 $2,500 minimum fee)Max Loan: 65%-70% of After Repair Value(ARV) 100% Rehab Financing Available (Require 20% of purchase price down payment or cross-collateral)Closing Timeframe: 48 Hours - 3 Weeks (Most Deals are 2 Weeks)NO PRIMARY RESIDENCES, NON-OWNER OCCUPIED ONLY, BUSINESS AND COMMERCIAL USE ONLY.

Although this would cost me 15% the flexibility of not having to rush and find a property within a certain time frame is attractive.

I learned a huge lesson here - don't buy "renovated" 100 year old inexpensive  homes, especially OOS and sometimes it is just better not to do a deal.
