Welcome to the site and glad to see another fellow Westchester Resident.

With small multi-family, be careful with the neighborhoods in Indy as it is very street by street in some areas.

He told me they don't care if the houses make money, only that they more or less hold their principal because what we think of here in the US as volatility is laughable to most of the rest of the world. 

I could care less if someone smokes marijuana but worried it might impact other tenants & future renters.What are my options, if any?

One of the best hacks if you have limited cash is to buy a primary residence with up to 4 units.  

I can or have already looked up citizenship, residency, taxation, crime, inflation, etc.  

For example, the FHA will all 100% financing on a purchase anywhere in the country, not just in the disaster area, for someone residing in a disaster area at the time of the disaster, whether they were a homeowner or renter.

Fannie/Freddie do NOT care if you transfer your property to your LLC. 

Regarding leverage - use it carefully!

Do I care about your pro forma 5 years out that makes all kinds of optimistic assumptions?
