@Christian WeberTo answer a few of your questions,If the property will be vacant for more than 60 days, then you will want to go with a Vacant Building or Builders risk policy depending on the rehab detailsPersonal Umbrella policies can get picky going over out of state or vacant buildings.The most common limit for General Liability is $1M.

If you do decide to go with working with each other.There are two ways for multiple people to own property - Tenants in Common(TIC) or through an entity(Corp, LP, LLC, etc)Best of luck!

Again, check the laws of your state about deposits and see what is common.

What I've done is if there is interest I just send them a message with everything including answering common questions.  

I do not have anyone within my immediate circle that could lend me money for real estate and after joining a lot of groups on Facebook and looking around, it seems like most "private money lenders" on there are scams.

The common advice is you have to hold on to it for at least a year to to qualify to play it safe though it's not stated in the law.

But shockingly not all Private Money Lenders are sneaky scam artists.

Is this common for nonconventional lenders?
