I would absolutely help an investor buy a property and then manage it.

Me and my clients all use a low money down conventional mortgage (as low as 5% down) with NO PMI and extremely low closing costs. 

And early on post-covid it absolutely ripped up.  

The problem is: A traditionally financed low-down payment house-hack with traditional long-term rents simply won't cash flow during occupancy, or after, in many MCOL-HCOL markets in the US. 95% leverage at even 5.7% just won't work in a lot of cases right now.

There are quite a number of things that can make utilizing an FHA loan more difficult such as more barriers during appraisal, appearance of low qualification/little cash, typically longer closing period, likely higher interest rate, and PMI cannot be dropped without a refinance if 3.5% down.That said, just chain 5% down conventional loans, and make sure your duplexes pay for themselves.  

BUT The points they charge and interest are both way higher than normal, on some deals I ran numbers the points and interest were going to be 20k on properties where the ARV is 100k so you have to get properties at such a low price to make it work that it is so hard.

A a low-temp sensor be added for you to be called if the temp falls below 55º ?

You are absolutely correct - I have never done this exercise. 

@Jeanette LandFrom my experience working with over 400 investors, growing your portfolio with limited capital is absolutely achievable with the right strategies.

Absolutely, I am taking great pride this year in making content that is not microwaved from sourcing a few google articles that "gurus" just reguritate.
