They want to start out wholesaling in their spare time to build capital to buy long term rentals. 

But would like to get some insight and details about that market as I live in the Denver area and will be long-distance investing. 

Use Private money to acquire and then refi into long term debt

Also how long would I need to rent it out for to be considered applicable for an 1031? 

Would I be able to do a 1031 if I’m buying a primary property with an ADU that I would use as a short term rental?

I've closed loans with entities way less than 6 months old.You have a long road ahead of you of you can't bring the capital or credit. 

Meaning it may not be a traveling, nurse, but definitely a shorter term lease.

Hi all, I'm buying a new construction via a 1031 exchange as a long term investment property. 

We do not represent them.And I can tell you, in almost every case we have an unrepresented buyer on my listing....I make more, the seller makes more....and the buyer is probably paying more than they would need to, and waiving things, or agreeing to contract terms that they have zero idea what they mean or is customary.As an example, almost every unrepresented buyer on my listings ends up paying 100% of the transfer and recordation taxes, when customarily those are split 50%/50% between buyer and seller.

Generally if you are looking at a rate-term refinance (i.e. less than $2000 cash-out or just refinancing into a long-term lower-rate loan but same loan amount) then you should be fine - if looking to cash-out on the refi - generally will need to wait six months of seasoning however there are a few lenders that will do cash-outs at the 3 month seasoning mark
