Probably depends on the location and part of town if neighbors care or notice. 

Therefore, I try to find a more user friendly web site that can distill the above into something that is readable.  

Use a promissory note drafted by an attorney to outline loan terms, including an interest rate that aligns with IRS Applicable Federal Rates to avoid gift tax issues.

Depending on your market, you can look up sold properties on Zillow.

This question is definitely very location dependent - licensing across state-lines is a tricky thing to navigate so depending on the size of the lender they may operate in one metropolis or all over the country.

I'm in the no pet camp, but some of it depends on the property.

Depending on how much equity in the property would be key as you cannot borrow 100%, if its investment property 80% is max typically. 

Would depend on the full situation though if that would be possible.

It'll be property specific depending on the condition but I'd say anywhere around 5% is going to be a number to start with. 5% cap ex. 8-10% for management. 5% for vacancy.
