What I would like to do is to change this to exhaust outside.  

If I help my landlord with simple maintenance, caulking, fixing can light fixtures, replacing an exhaust fan, can I deduct on my taxes the material costs and or labor since I performed this work for a rental property I do not own?

I checked the forums, but couldn't find an exhaustive resource for legal requirements.

After you have exhausted conventional mortgages ( or in between loan availability) you start looking for PML and owner financing for long term loans.  

That type of policy provides an additional layer of Liability coverage (usually in $1,000,000 increments) that start if the primary policy's Liability limit for the location gets exhausted by a claim. 

That sounds more like a loan/gift than an investment.

(It'd probably suit an owner-occupier rather than an Investor).If its return on market value doesn't gross much more than 0.5%/m, I reckon it's not a good candidate for refinancing.

It is exciting, risky, and exhausting but the rewards can be limitless.   

IMHO it's much easier being an intentional landlord than an accidental one.

Various ways and databases to look in to find claims history.I dont work a lot on the commercial side, however know the underwriting guidelines are a bit more exhaustive vs a typical residential policy.As Chante stated, make sure the incident was a covered loss, and keep in mind if it hailed more than once, or there was a wind storm one month, tree branch fell the following week, then a hail storm 2 weeks later all in the same summer - those are 3 separate claims/events.
