Thanks,Ratna what everyone mistake is some people is stuck in h1b for decades and they are too afraid to buy primary home, or to buy rental in US or even to apply mortgage which at the end, makes them losing the biggest opportunity to make money in real estate.In reality it doesn't really matter as income from cash flow is a passive investment, you could do even flipping business while on h1 as the profit is from buy and sell activity. 

We have a single family we BRRRed (ish .. we ended up selling on contract rather than renting) and a 5-plex here locally.

Ana, to my knowledge, you won't qualify for a 1031 exchange unless you sell the property.
