My guess is that's what draws others here too.

So in your whole town you probably looking at about 1000 potential renters, and they are the top 15% of the 50% you can draw from. 

Can anyone personally sum up (or point me somewhere) the benefits and draw backs of the different ways taxes could be handled in a SF house hack?

I can't imagine this lasts long.Provisions of existing lease are as follows -- I created a rules addendum document that says "The following items are not considered wear and tear to the premises, but is considered damage to the premises; subsequently the cost of repair will be deducted from any security deposit." 

Origination Points 1,421.81Company Consulting Fee$997.00 NVMS 0 $0.00 Admin $200.00 Loan Servicing Fee$180.00 Draws$0.00 Misc.

Besides all of the things you mention, a local architect can also tweek plans for subsequent homes based on experience building home #1.  

Personally nothing frightens me more than investing in the sticks with no real draw and nothing but tumbleweeds. 

Note however, that if you improve an apparently abandoned property and the legal owner, or an heir to the legal owner subsequently shows up to claim it, the courts will generally not enforce reimbursement for the improvements you made to property you did not own. 

Similar to when you draw down on a heloc and your credit score goes down

There might be other costs like appraisal / BPO, property inspection etc.Few lenders give 50% of construction costs are post reimbursements in draws and few does higher percentage of coverage on renovation costs.Ask around and see what works best for your situation
