If you want in-person training and office culture, you want to focus on more traditional models like Keller Williams, Re/Max, Coldwell Banker, but you will give up more of your split there.

Here are my recommendations when screening a GC: 1) How long have they had their license, minimum 5 years; 2) check their work - if they only do kitchens and bathrooms (although important) they don't have the well rounded experience for a total rehab or addition; 3) make sure they are insured/bonded, this is actually to protect you - not them; 4) stage the work along with a payment schedule, don't be pressured into advanced payments except for materials; 5) identify all tile, carpet, paint, fixtures and appliances by SKU# and/or model number in advance - this keeps them from putting-in cheaper, inferior product; 6) along with item 5, avoid MDF - especially in kitchens, bathrooms, laundry rooms, exterior door and window trim; 7) lastly, after qualifying the GC, get at least 3-quotes. 

House hacking by the room rental can certainly be cash-flow model in Denver, but I wonder how scaling works beyond a handful of those.

I am planning on going with a Buy & Hold business model and am wondering what things you wish you knew when you first started.

These are all rough numbers and we don't have enough info on specific payment amounts and savings rates to do a discounted cash flow model to arrive at a more precise answer, but I'm fairly confident the DCF will say a similar thing as the back of the envelope math. 4.

I highly recommend it as it is a simple business model, though it does require hard work like all things worthwhile, and it's been quite good to me & my family.If I can be of any assistance or if you have any questions or concerns - please reach out to me.

I say stay on it bro, and I'd say only get rentals witha 3bd 2 bath setup or better, there definitely going to have longer term tenants, many authors mention this model also.

All investors are having to take a step back and re-evaluate their investing model, make tweaks, and move forward. 

If you can point to a proven business model that is de-risked to a large degree with a sponsor team with a track record of success operating together on the product type you're presenting this is a lot different risk/value proposition than if either the product type is new to you, the product type is new or a hybrid, or your team is new.  

(I had some clients do a rent-by-the-room model out there last year and they're crushing it.
