One thing I wish I'd known at the beginning: spreadsheets, and calculations, and all that are based on assumptions.

Also, and we aren't wired to file many insurance claims but my assumption is that actual home insurance doesn't cover typical items that require maintenance over time? 

Also, the property is in an okay neighborhood.Values with squigglies are estimated.Asking Price:  $94,500Closing Costs:  ~$2,500Rehab:  ~$500Down Payment:  20% ($18,900)Prepaid taxes, insurance, and interest:  ~$1,000 (not sure how to estimate this so this is just a guess)Initial Investment:  $22,900Mortgage Remainder:  $75,600Mortgage Interest Rate:  ~4.5%Mortgage Period:  30 yearsMonthly Payment:  $383.05Monthly CostsProperty Taxes:  $167Insurance:  $50Utilities:  $0Lawn Care/Snow Removal:  ~$50CapEx:  $100Vacancy (5%):  $61.50Repairs (5%):  $61.50Management (10%):  $123Total:  $996.05Total Monthly Rent:  $1,230Cash on Cash ROI:  12.3%Do my assumptions seem reasonable?

It will depend on the current condition of the property and quality of tenants.The Future Assumption Information makes this more confusing.  

Any information or assumptions would be appreciated.Thank you.

There’s also this assumption that interest rates will be the same, access to capital will be just as easy, etc.

If you are not on a tight time frame to close then I would not use a broker but considering most of time hard money loans are involved with cash offers I am making the assumption you probably have 2-3 weeks to close. 

The assumption here is an investment property but maybe not? 

. #2 can also happen if your assumptions are incorrect. 

You didn’t mention the amount you paid for the property and in the absence of additional information I question if the valuation based on the 10% cap rate assumption will hold up.
