The median price of a home in Los Angeles is now around $1 million.

Here is some FACTS to chew on, yes, from an immigrant household who has actual 1st hand current experience in immigration. 

Hello @Jared Leggett,I agree with @Nicholas L.Westchester and Suffolk Counties have median multifamily (2-4 unit) pricepoints that are about $200K below what you'd find within the boroughs (excluding the Bronx & S.I.).That said, it is possible to househack in these markets with ~ $50K.

Median sales price for condos and townhouses is down -3.4% YOY in October in JC.

The national median rent-price ratio is about 0.35%.

Stay with properties at or below median value within 1/2 mile maximum of the subject property.  

I am in Madison, but set up a search in Sheboygan and Port Washington as we have some family in that area who thought could keep an eye on things and the entry prices are less (in Dane County the median MLS 4-unit sale this year is $603k with 31 sales and for Sheboygan Co. this year only saw 4 sales of 4-units noted, but a median price of $252k . 

I've communicated with other agents in Nevada that provided me data with median rents, cap rates, how much I would need to put down to get it to "cash flow/break even" with higher interest rates, etc.

Does anyone have some really good websites for accurate up to date data for vacancy rates, median rents, average household income, etc? 

I generally rule out most single family homes as viable rentals, as prices are pretty high relative to rents, so aside from some downtown neighborhoods, typically you do not find large areas of single family rental neighborhoods (a median sale price on a 3 bed, 2 bath home so far this year in Dane County on MLS sales data is at $430k).
