Here are some key factors to consider regarding the potential resale value of a real estate investment:

1. Location: The location of a property is one of the biggest determinants of its value. Prime locations with good amenities, transportation, and desirability tend to appreciate more over time and command higher prices when reselling.

2. Condition: The condition and updates of a property also impact its value. Renovations, renovated kitchens and bathrooms, new appliances, etc. can add significant value. Properties in original or outdated condition tend to sell for less.

3. Comparable sales: Looking at recent sales prices of comparable properties in the same area gives an indication of the potential resale value. This helps set realistic purchase price and future sale expectations.

4. Supply and demand: The balance of supply and demand of properties for sale in an area affects values. High demand and low supply push up prices, and vice versa. Areas with strong long-term demand tend to have better appreciation potential.

5. Economic factors: Macroeconomic trends like interest rates, job growth, and the overall health of the real estate market impact resale values. Properties tend to sell best when the economy and market conditions are favorable.

6. Property type: Certain property types like single family homes and luxury properties tend to appreciate more over time, while others like condos see more fluctuating values. Type plays a role in potential future sale price.

Those are some of the major factors to evaluate when analyzing the likely resale value of a real estate investment. Location, condition, comparable sales, supply/demand, the broader market, and property type are all important to consider.
