Sometimes certain things fit a little better depending on what you are doing.Also, I might suggest that if you need something on a local level it's usually better to get this from another local real estate investor. 

I recommend a simple spreadsheet to check your math and it will make it simple to adjust each year.End the complaints.

We suggested they start a business and buy through the business name but aren't sure about that either. 

So, I would suggest to get with a realtor to help you find the specific neighborhoods that might fit your needs.  

I strongly suggest you create an LLC for each investment property you have that way if the loan goes sideways and they have to foreclose, they can only go after the specific asset and not your whole portfolio. 

Two things I'd suggest is to keep house hacking and dollar cost averaging. 

I don't have any particular day or time in mind yet so any suggestions are welcome. 

I agree with Bill's suggestion regarding requesting tax returns and bank statements.

Suggestions are greatly appreciated!

I would suggest that you check out some local meetup groups in your area.Good Investing...
