So far, it has delivered on expectations.

GrumpyHare delivered on their end.

You always want to think about what the guests are looking for and tailor the property to that.

The contract should have outlined the amount of earnest money you deliver.

And you can't be of service, if your not delivering value, so one will make themselves of value. 

Now my focus is on heavy rehab mix use/ multi-families that can be delivered below replacement costs and  $400/sf+ outsale new construction opportunities.

Given your experience and strong financials, you have some solid options:Commercial or Portfolio Loan: These are tailored for investors and can help you avoid personal guarantees, especially since you have an LLC.BRRRR Loan (Buy, Rehab, Rent, Refinance, Repeat): Some lenders offer BRRRR-specific loans with funding for purchase and rehab, allowing you to refinance based on the new ARV once stabilized.HELOC or Cash-Out Refi on Current Rentals: Tap into the equity on your single-family rentals to secure funding for the 4-plex purchase and rehab without high origination fees.Each has pros depending on your cash flow goals and timeline.

Also understanding how things are put together, how siding works, gutters, etc (basically as many aspects of the home as possible)Having this knowledge will also help you from getting burned by contractors telling you things just so they can save time and money and deliver a crappy service. 

Will mail be delivered even if A and B are not officially registered with the USPS?

However, there are still some great opportunities within Charlotte that can deliver strong investment potential.
