I'll be selling my own investment property for $245k.

So I am having my own software developed to provide the broker a turnkey solution to selling my securities.  

I am in Virginia and found a development with several lots selling for around 5-15k.

Sell just the buildings and keep the land.

Initially, when I started in real estate I could never understand why a seller would sell a property for nothing down or other advantageous terms to an investor.

For example, if you have overgrown grass at 123 Main st they will stop you from selling 456 east street until the violations on other properties are corrected.

Are there other strategies you can use if the flip doesn't sell right away for a profit? 

Knowing your exit strategy is essential, regardless of whether your goal is to keep onto the property for the long term, sell it for a profit, or switch to another investing approach.Your choice will ultimately be based on your tastes, risk tolerance, and investing goals.

I can listen to books and educate myself on whatever I want while at the gym, in the car, etc.A couple I'd recommend to you based on your post are..FLIP - How to Find, Fix, and Sell Houses for ProfitThe Book on Flipping Houses How to Buy, Rehab, and Resell Residential PropertiesThis book is not currently available on Audible but a must readThe Book on Estimating Rehab Costs - J ScottBigger Pockets has become one of my best resources.

I think you either sell or go one of two routes.1) Plan to hold for at least 5 years.
