Last short term rental we put on the market was booked for a 30 day stay first day on the market.

Recommend they all do on a work day at the same time.  

You’ll have 45 days from your sale to identify them and you’ll have to buy enough of them, and only them, within 180 days of your sale to meet your 1.1M requirement, or face taxes.

I fully explained by situation and he assured me that they provide mortgages for non-resident citizens.I submitted my paperwork for pre-approval that day and waited.

I think it is fair to say that there is somewhat of a tradeoff between markets that provide positive cash flow on day one and relatively high appreciation-based markets.

build to rent is great. they are an intermediary that help investors contract direct with turn key new build. they are pretty sophisticated we have sold a house so far and we are looking to sell other multifamily with them. there is a vetting process and as an intermediary they don't control construction they help vet builders and establish relationships. they have a big team. the other builder I've never heard of but unless you can see your house I wouldn't touch it. rent to retirement has a strict policy of 90 days until certificate of occupancy until they will send a deal out they are good at what they do and I'd recommend them. they have options all over the country and established relationships.

The 45 days identification time sometimes presents a challenge and if you dont give yourself a little wiggle room you might end up buying something you dont necessarily want/like.
