I have been practicing my deal analysis daily, but it's hard to tell if my numbers are accurate without comps. 

Use those for your analysis. 

Occasionally you might see commercial real estate companies put out analysis for different markets and different commercial segments. 

Did you also do an analysis?

If I go BRRRR I’ll refinance with a standard lender.Assuming we sell for $625k which is the ARV and market analysis I pulled, purchased for $345,500 and have $120k in reserves for rehab cost.

A rental property analysis can give you a different perspective. 

I just did an analysis of 5 PM Software Tools for DIY Landlords under $20/mo.

@Doug Bontrager what rent analysis have you done?

Financing- build a relationship with a regional banker, don’t shop for interest rates, start small and build history and loyalty they are your team, Cross collateralize, deposit CD/MM or custodial account with bank for loan, give them monthly updates, nail your deal analysis, do stress tests on your deal analysis-cost/interest rate/deal length/ sale price etc. 12.

If information is limited, use market-based assumptions to run a "worst-case" analysis.
