I assume a higher upfront cost as far as land purchase and the actual build but you would have a brand new house, instant equity and hopefully maintenance free for quite a while.

Alternatively, if I can find a lower cost single fam home where I can cash out 100% of my investment I would do that but those have been harder to find recently. 

One of my connections will fund the rehab for less and give it all to us on the upfront to finish the project at a lower cost.

In other words, you will incur the cost of demolition just to get the raw land.  

Quote from @Daniel Gould: So it appears to me that while there's a free plan available to anyone in Invelo but the BP Pro membership includes access to the "Starter" Plan which currently costs $41/month otherwise - so this is a notable "value add" to the BP Pro Plan.

I understand they are planning to to offer recordkeeping and plan document maintenance services to Quest clients with no cost to transition. 

But from a moral & ethical perspective, you may want to decide at some point to just eat it and accept write it off as cost of doing business.

Going this route is more involved and that makes it more costly too.

The cost of labor , materials , property taxes , inflation , interest rates  etc .

If you own 25% or more of any LLC you are required to register with a FINCEN ID for beneficial ownership by January 1st or you could be subject to $500 per day fines.Have you taken care of business?
