I used to use spreadsheets, then moved to when QB as my portfolio grew, now on Digb because I have multiple LLC and I don't want to have to buy QB subscription for each.

How are most investors strategizing there (fix and flip or buy and rent)? 

I have given some very strong consideration to buying in Detroit.

Quote from @Emma Campbell:If we have a Lowes business pro account, and in Month 1 we buy $1000 of materials for properties in 3 different LLCs, it sounds like manual effort is needed both to pay off the $1000 balance by making payments from each LLC's bank account for the amount it owes, and then a separate manual effort to record and assign the expense transactions in the bookkeeping software.

After we live in it for at least a year, we will move out of the 4th unit and buy another multi-family and do the same thing.

However, if I sell my business then do I no longer qualify to buy a property in the future?

You can use either a wi-fi smart lock or subscribe to a system like ShowMojo, ShowingHero, TenantTurner, etc that uses preprogrammed smart locks.

This means that you will probably need to pay registration and filing fees in at least 2 states if you don’t buy CA property as a CA resident.Any lawsuits should be limited to the assets of the LLC and not your personal assets (assuming you run the LLC appropriately and the corporate veil is not pierced, some debate as to SMLLC).

@Tim JohnsonThere are essentially two ways (and a few variations) to purchase this deal, depending on how the owners are selling it:As a going concern:  In this instance you are buying the business, so it is the business you evaluate: assets, liabilities, revenues (historical: 3 - 5 years), operating costs (historical: 3-5 years), future financial projections, goodwill, etc.    

I have a current tenant who would like to buy a rental house he's leasing.
