So I think that's the "sexiest" change... though I also agree that practically, the best thing would be adding that shower (and that would be some forced appreciation on the house, too).  

The $100K would be added to your taxable income for the year and there would be an additional 10% penalty for early distribution if you are under age 59 1/2. 

I always grout, then a bead of clear silicone where the tub meets tile (over the grout).

While operating usually about 2% of gross rents are required to be added to the replacement reserve account held in escrow.

The tenants boyfriend is now interested in staying in the unit but does not qualify to be added to lease.

So, if the payment is $150 on the entire 65K then that number will be added to your total debt payments.I hope this helps and have a great day.

Risks that I see are rent control (already in some places), lessoning housing regulations (there is a proposed regulation that would let any SFR be converted to a duplex, there is already ADU rules that allow an ADU to be added to most SFR, and parking requirements are constantly being reduced to allow more affordable building options), possibly at top of market (which if past history is an indicator even if Bay area is at top of market a new high will be established in no more than 8 years), potentially any number of other potential Landlord unfriendly regulations (no STRs, disallow criminal checks, rent control (already discussed), longer more onerous eviction procedures (already can take a while in some cases), mandating acceptance of Section 8 (already true in some areas), etc.).You evaluate the return versus the risks and determine if the investment appears sound. 

Direct message me if you want to chat or if you want to be added to my buyers list.

If there are no such liens when I buy the property, what kind of liens can be added later?

My lease is 9 pages and soon to be 10-11 thanks to all the stuff California politicians keep requiring be added to the lease.
