I would pretty much exhaust all my cash with a cash purchase but would have a house worth at least 55-65k.Or, do I use less of my cash to buy a 70k rental that needs less work?

After owning them for 5 to 7 years, we made the move to sell, and did a 1031 exchange into an 18 unit property that I found after an exhaustive search in the same town.  

It may be "normal" but it sounds more like a formality than an inspection.

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.
