In order of decreasing importance, I worry about liability from burns on children/pets (they get ridiculously hot while operating), risk of house fire (like if they lean something combustible against it or do not provide a wide enough berth around it), and smoke damage/deposits on the walls from improper use/air mixture adjustment. 

Although many variables are valid the statistics support that the market is not quite heading for a 2008 type collapse or adjustment. 

Ultimately to start out cash flow will be an important factor as well to speed up my ability to reinvest as quickly as possible. 

I think offerpad was 6% closing fees and 6% “market adjustment” last time I got a quote from them in Las Vegas.

They could close in title+4 days, making it nearly as fast as cash for on-market deals.Something like that through a small local bank looking to get into the investment real estate game could be a warp-speed-ahead button.

If you feel the market is going down, wholesale, or adjust your numbers to the decline, and "meet the market, don't beat the market".

The first thing that speeds you up is getting from theory to practice.

Also If I ask the adjuster the above question what's the risk that my broader home insurance claim would be rejected since I had this house on short term rental?

Make sure you are asking about all the terms - the maturity date, the adjustment period, the costs, etc.  

I made an insurance claim with my insurer, Foremost, but haven't talked to an adjuster yet.Is this something that I'll have and problems with getting covered?
