Are permits for developing condo buildings and big projects different from developing single family homes and/or townhouses?

To mitigate the obstacles of investing out of state I would recommend getting a good project manager.

In general, SFR will never cash flow as well as duplex to quad.What I did not see is your cash flow projections (ROE), COC projection.I suspect that this property is not the best candidate for BRRRR (Refinance versus selling) but best to sell it. 

Construction, for example, will add risk to a project because it limits the capacity for collecting rents during this time.

I have a guy that I have do all my projects.

in Jacksonville Fl for example, contractors run 14 days behind to look at your project, if you get a response at all...and don't just go for free, and agents are busy..Care to share your secret or strategy?

It's tough waiting out the clock but with several active projects and a pretty good pipeline time flies by.

I project that I'll be able to invest in another multi family in another 2 to 2.5 years. 

The increase is from $50/unit due to the "Clean water Atlanta" project, which mirrors the numbers you mentioned.They compare Atlanta to NY, and if my tenant's usage approached the average usage, I'll be paying almost as much as you.

For any property with 2 or more units, 85% of the projected rent of the other units must be included in the homebuyer’s income.
