Buy & hold is a very forgiving business model and as long as you buy a quality asset that cash flows you will be fine, no matter what the market does.

Hi, I'm looking at these companies and really not understanding the basic facets of the business model.  

These can pose to potentially have of problems but a lot of investors in my area are still purchasing such properties, probably by expertise in knowing what to expect in older homes.Either way, i would pay attention more attention to products built in the 1920's than those built in the 1990's etc.

You have no idea if that person handing you a contract to use has the expertise to write it. 

Tariffs are a factor, mainly on certain materials like steel, but not a huge factor overall   Without knowing many of the specifics, or finish out levels of your project, I would expect to be able to build something like this for around half of what you are being quoted.My guess is the reason for high quotes is that because the demand for construction is so high, and contractors are backed up with as much business as they can handle, they are throwing out very high prices.I would keep shopping, and if you have experience, consider GC’ing it yourself, and hiring the expertise in the places you need it.

I understand that a lot of companies are moving to a monthly pricing/subscription model. 

Local real estate knowledge, contractor contacts and other expertise.

I very much so value your expertise and advice.Sincerely,Chace Marigny

While private land is not my area of expertise, it would make sense to me that if the rehab covers certain areas of the home, the answer would be yes.

Buying rehabbing and selling houses and buying multi units to rent are completely different business models.
