I am most likely going to go the FHA route and I am wondering if I should try direct mail to find deals or what the effective methods are that successful investors are using in this area to find great deals.

I am not sure how many people do the BRRRR method which this is primarily for.

Conventional appraisal is tied to the financed amount, so a larger down payment might solve it.Is the appraisal right? 

You don't want to hyper focus on one single lead gen method or one single isolated niche because in time it may come to a dead end.  

They have to connect to an internet connection but you can easily solve that by setting up Wi-Fi in the house or using a cell phone hotspot.

Can anyone offer advice on execution or creative finance strategies that would solve/avoid this problem? 

They require 20% down.  15 or 30 year.I'm not endorsing, just passing on what I'm looking into, as it seems to solve some problems for me.

If you are considering this type of investment, the quickest way to analyze cash flowing properties would be through the four square method. 

Does anyone have advice on what other creative financing methods I could use to fund my purchase?

If we sell that same property in 30 years but on the 30-year, 3.125% rate we make a total profit of $497,000. 30 years down the road and $38k richer via method A but the Coc at the top of the report is only 4.27%(our report) for this one opposed to 10.97%(the one you can't see) Coc return for option B.Let's look at one more metric that stuck out to me, that is CoC return for year 30. the 15 year/2.5 loan(the report) at year 30 generates us with a 41% Coc return, which seems like an astounding number to me even though I probably couldn't fully explain what is happening.
