Landscaping, installing a patio or deck, adding outdoor lighting, and improving the entrance can boost the overall value of your property.Basement Renovation: A finished basement can provide additional living space, which is always appealing to potential buyers.

This was at my first VR, in a small town by the entrance to Sequoia National Park in California.  

@Nathan Florence I would say buy a single family that needs work, ideally with multiple entrances, or the ability to add more units.

Some people don't go thinking it's an entrance fee.

If you are buying for a long-term investment, you will do very well.Can the home you are interested in buying be split into a main home and an in-law/studio with a separate entrance?  

I'm on the lookout to buy a SFH in this crazy market and I'm looking to buy a split level home that can be converted into an attached ADU (upper and lower level living) with its own entrance. 

You might be able to make single family fly with a seperate entrance. 

Something like " the below grade area has its own entrance and is finished as a third unit with four rooms and is reportedly rented as a separate unit" it is beyond the scope of this analysis to determine if this is a legally permissible separate unit however county assessment records do not mention it, so I have assumed that it is not legal and given no contributory value" or with the ending " If found to be legal, the space would contribute $xx,xxx to the subjects market value." 

The additional parking, separate entrance, and finished basement would allow us to rent out the space without sharing our living area with the lessee (If we ever needed/desired to rent out that basement in the future).What would a seasoned real estate investor do in this situation?

I'm a local agent here that specializes in house hacking, and it is an amazing strategy that will help you accomplish your financial independence much faster than just pursuing index fund investing.Since you are looking for single family property , have you thought about finding house with ADU, house with separate entrance, house with mother-in-law apartment?
