It  depends on your risk tolerance and what other assets you’d like to protect.

It depends on your financial strength, the quality of the property, how many properties you own, etc.I like to start with one significant expense and three months of vacancy.

Quote from @Jaren Taylor: Quote from @Stuart Udis: Depending on the transaction sizes you are pursuing, raising money to purchase property without debt requires either an incredible network of relationships or devoting a lot of time and effort to raising money.

And it depends on what you do next - rebuild or sell as is or some other plan. 

Quote from @Chris Seveney: @Charlene Kingsnorth have you had an sec attorney also review what you are doing as if you're are having multiple people as part of a loan participating in it depending on the state this could get you in hot water - so be careful  good point Chris some state allow fractionalized deed of Trust mortgages other do not or require PPM like documents prior to offering them..

We have many efficincies under management with a ~10% vacancy rate with prices ranging from 485-625 depending on location property quality and amenities.
