I also have this same question, but I'm looking for something not cloud or web based, an actual installable program my logic is that I'll be able to create an Air gap between vital information social security numbers/EIN's  bank information account balances and such to keep it from being "hacked" 

I'll assume you understand what is and is not eligible to invest in an OZ and what the benefits of doing so are, and your question is how to do this yourself for BRRRR properties you buy, rehab, etc...rather than just dropping it in a fund (of which there are many, and that's definitely the easier route, though less 'fun').OzToolKit is the best explanation on the web I've found.

Import my bank account infoImport my credit card infoImport mortgage statementsImport insurance stmtImport personal w2Import my completed taxes I seriously doubt you you will find everything on that list… much less question why you would need to import a w2… but with that said, we use Rentec-Direct… it is a full service software… collects your rent, tracks all expenses, balances cash / checkbooks, screens tenants, has a tenant  facing web portal… and it really cheap compared to other paid services.  

That said, you will need to refinance off FHA to clear your 1 FHA slot to then do the new purchase with FHA again. 

They do have a phone/tablet app as well as a web interface.

IMHO it's more important to take action on the "how's" than spend too much time tracking 5 different metrics or spending too much time analyzing goals or creating even more that likely won't get done.Another great tip-- put EVERYTHING on your calendar so you have specific time slots for all the "how's" you need to get done and stick to them.

I've googled and searched all over the web and found nothing.

Using API's, GIS, webs scraping, and others is both interesting and challenging.

No more investors can step in at that point on the other units if they want to use a loan to purchase.Maybe I'm worrying too much about it since, if I own a unit as an investor, and I want to sell to another investor, they can still purchase it because they can just take my "slot" as one of the investor units.How much does that situation dissuade investors, if at all?

But for most individual values I used google to check those numbers (mostly from home repair web pages/blog posts posted in 2021 or 2022, as recent as I could find them).
