Below is my estimated scope of work and timeline.

Assuming your numbers are accurate, I'm estimating your monthly "rent" or your contribution to the monthly expenses will be about $2,000.

I know a cost segregation study would be too expensive for such a small amount of property, but is it permissible for me to estimate the value of the components on my own?

The estimated value  now (roughly) is $200K. 

@Vincent WeselakIt’s a good idea to get an estimate for your insurance costs upfront since this can vary based on the property type and location, and it’s a key factor in evaluating your cash flow. 

For me the area I was concerned with was estimating costs.

They can send you comps so you can confirm the estimated ARV.

DIY A first-time DIYer can expect to spend several hours replacing a kitchen faucet.The time it takes depends on your experience and the faucet's complexity.You'll need tools like wrenches, a putty knife, and a small bucket.You'll also need materials like supply lines, silicone caulk, and plumbers tape.You may be tempted to be cheap and estimate only 30 minutes, but you should estimate an hour to be safe.What about the time to go to the property to figure out if a 2-hole or 3-hole faucet is needed, then drive to Home Depot to get it, drive back to install and then head either to the next job or back to the office?

On the surface, the deal seems appealing, but there's a catch: the asking price is $475,000, which is about 18% over the market value (based on comps and DealCheck estimates around $402,000).Details of the DealProperty: Duplex, 2,400 sq. ft., Purchase Price: $475,000 ($197.9/sq. ft.).Estimated Market Value: $402,000 ($168/sq. ft.).Financing Terms: 2% interest rate, with a 9-year balloon.Unit B Income: $2,049/month (Section 8 tenant through November 2025).Unit A Income Potential: Similar rent or higher; Section 8 cap for the area is $3,234/month.Monthly Loan Payment (P+I): $1,386.Cash Flow Breakdown (if both units are rented at $2,049/month):Gross Rent: $4,098/month.Vacancy (10%): $410/month.Operating Expenses (37.3%): $1,376/month.Net Cash Flow: $943/month.Key QuestionsWould you be comfortable paying an 18% premium for financing at 2%, especially in a market where current mortgage rates are closer to 7%?

I have all three kinds of parks- LT RV, POH and TOH so can help with repair estimates but so much depends on location and access to reliable repair services.
