I think a lot, especially when reading, listening to youtube/podcasts, or even just laying in my bed before I go to sleep.For anyone that wants to, please step in and tell me where the flaws are in this plan.

My Background I am 29, single (living with roommates in a 4 bed, 2bath SFH) working and living around San Jose CA (bay area).

In this area, that is high for an 1,147 Sqft, 2 bed, 2 bath that will need a PREMIUM facelift, as in the structure is still good but most everything will be replaced but the studs due to everything being outdated.

For example, I manage a similar 2 bed/1 bath basement close to me that chose not to furnish it and do a long term tenant, and it rents for $1250/month.   

For furnishings other then a bed check out consignment shops.

As your unit is a four bed/2.5 baths, you will definitely attract more families rather than individuals who rent with roommates. 2-3 beds tend to attract the latter rental group and with the larger amounts of beds and baths, that's more appealing to a larger family renter.First couple is obviously out - too many people and it does not seem like they're qualified.

The property is brick, built in 1980s, 3 bed 2.5 bath in each unit totaling 6bed/5bath. 

My first and only house is a 3 bed/1 bath single family.
