possible big upside for the current SAFE agreement holders.Brentwood.com is a current investor in Lazy Dogs LLC and wants to take it public in a few years. options usually are good for 10 years and at a current Valuation IPOs can go !

I have one I've used on 7-8 of my transactions 

Obviously it is always a good idea to respect folks time, but find someone who also has skin in the game, investing where you are investing, can talk about their experiences, and also has built a network of folks who can support you after the transaction as well. 

As long as its common and customary for the area to rent out those units safely, then you can open up a whole new inventory to look at.

Upon BP member recommendations, my husband got his real estate license which now helps increase our access and decrease our transaction costs.

thanks for your time and help rent to retirement works directly with build to rent developers like us around the country once they are framed up. you are buying properties pretty much at market value but with a hand holding. you can work directly with a builder or directly with them. they are just an intermediary. they take 5% on what we make as a builder but have a large list of investors and a systemized approach to selling new builds. if you want to get a better deal I'd recommend directly contacting builders and building it yourself. fly to the market. spend 2 days, tour new builds, get a feeling for how it's going. if your builder isn't building multiple at a time then I wouldn't recommend working with them. rent to retirement is a well oiled and well run machine. they've had their ups and downs with dozens of transactions in florida but modified their process. they are well known and established and transparent. if you have a more specific market and feel confident in your ability to vet deals try it out. happy to talk more my info is in my signature. we work directly with them to sell new builds and no organization is perfect but I have good things to say about them as a builder and potential build to rent developer that sells build to rent triplexes and single family homes through them to end buyers in California like the Bay Area, Los Angeles, and San Diego 

To answer your question, I will use your description as it most closely relates to my definition of what an actual turnkey real estate transaction should be. 

I would recommend a real estate CPA specialized that knows how to handle sub to transactions.

It would be hard if it was just your son as the IRS might doubt it’s an arms length transaction.

Essentially it's totally dependent on the terms/risks that the buyer and seller are comfortable with and everyone understands the transaction.
