I had it at 2.5% (per my agent) right now i have both at 10% arbitrarily. how do i estimate Capex and Maintenance better?

Met with a GC for the 1st time this past weekend and needless to say, we're off  "a bit" on our build estimates.

The property currently listed for sale on their site shows a cashflow of approximately $144/mo but I feel like that number could easily be eaten up by Capital Expenditures.

Once our payments on the underlying note is approximately $4,000 this provides us a cash income of $12,700 monthly.

These are all rough estimates just to give you an idea. 

I did run the numbers on an estimated $500 a month insurance payment vs the $300 it will be costing my currently.

Approximately $25k per month, principal and interest. 

I'd estimate 50% of my investor clients during the past two years utilize professional property management companies and are very satisfied.

I called a successful investor I met at local meetups who helped me walk the property (first time for me) and estimate a rehab budget so I can run the numbers and figure out what I can offer in the current market.
