If so, which portion would get applied to the loan as down payment? 

203K Loans can be helpful but can take much away from the bottom line as there are many fees, similar to those of a hard money loan, that are incorporated into the loan on the back end for inspections, draws, follow up, etc, often times +/- $10k-$15k, depending on the size of the loan/rehab budget. 

On the Refi portion, it honestly depends on the ARV and estimated rents.

Assuming you are inquiring for the Myrtle Beach market, the average (across the 5 submarkets and all property types) is for 72.5% to require 2 nights or less (46.5% have no requirement).This is highly variable by ZIP code and property size/type, however.

-Cash reserves: Set aside a portion of your $50k cash as a reserve fund for unexpected expenses, such as repairs, vacancies, or market fluctuations.

I think that it honestly depends on the size of the portfolio.

With a substantial portion of this debt held by banks and regulators pushing for decreased exposure to CRE, liquidity becomes a pressing issue.

I have the sizes and am considering sound proof or indow inserts but really don't know much about them.

@Gino BarbaroI love your approach as I have a similar approach.Go big or go home isn’t always the right approach.As you note, in a market where one has a strong existing footprint, it’s easy to pick up additional smaller assets.That’s what we do in Greenville SC.It’s our only market and we own buildings that range in size from a triplex to 181 units - doesn’t matter to us.

While it is modestly sized and there have not been any deliveries or demolitions in the past decade, there has been some sales activity.
