One issue that I'm noticing is the range of reported insurance costs.

These traditionally have lower rates than cash-out refinances and will only cover your existing loan amount + closing costs, so you'll need an existing mortgage for this type of loan.4.

Coin jams are going to be your second biggest headache unless you invest in those fancy ones with tap-to-pay but those cost a pretty penny.

My favorite ones (as a Contractor) are those like : "How much will it cost to re-wire my entire house?"....."...

I think it was for down payment and closing costs.

CA maybe as high with their EIR requirements that cost 250k to 500k just for the EIR reports.

However, co-living allows you to acquire properties with as little as 0%-5% down, drastically reducing the amount of cash required.Instead of needing $100K+ to buy a rental, a co-living strategy lets you start with a fraction of the cost while achieving higher returns.3.

The primary risks at this point would be       1) to your lender, the risk of a margin call.       2) To you; underestimating the true cost of a project and cost overruns      3) To you; legal risk of securities regulations if you partner looses money. 

Costing them thousands and making them lose out on homes.

Of course have your costs researched first bc the buyer will want to know how much it will cost them to buy.
