However, I'm currently trying out Zillow Leases as it has online signings—a significant drawback to Law Depot. 

I know clients that are "dirt poor" they literally roll everything and never touch the money and have an incredible net worth - but no cash - and that is the draw back. 

That's always the biggest drawback from a seller's perspective.

House hacking does have its drawbacks.

Neither of these are really big drawbacks since you're planning on moving in anyway, and the down payment is so low it's not like you're going to pull out tons of your working capital with a refinance in 6 months. 

Little more expensive up front is the only drawback.  

People need places to put their stuff so unless you are installing medicine cabinets, shelving and linen closets a pedestal sink is a drawback.

Sure there are drawbacks to only using online comps, but the opposite is far worse.

The draw back to these loans is that they are more paperwork heavy than the other "portfolio" types of loans....but if you have ever received a loan on your primary home, it's likely that you will go through the same type of paperwork here with conventional lending.

-What has been your biggest draw back from working with wholesalers, when purchasing properties to flip?
