What's the ONE app you need to run your real estate business?

am new to real estate investment I have my capital ready but don't know where to start please guide me on how to start and which app to use

Actually, BOTH scenarios push this into commercial:https://guide.freddiemac.com/app/guide/section/5601.2See:(a) Ineligible property typesMortgages secured by the following property types are not eligible for purchase by Freddie Mac:A 2- or 3-unit property with an ADU that does not comply with zoning and land use requirements (illegal zoning)A 1-, 2- or 3-unit property with two or more ADUsA 4-unit property with an ADU

No Apps either.... :-)
