I would choose the strategy that best fits your strengths (unfair advantages) and what the market in your area demands.

Buy on market, nothing wrong with that.

It’s great to hear that you’re already active in the Southern Maine market.

From there we identify properties that could have some potential and if you are interesting in diving deeper, 1) we do a thorough video walkthrough to give you a realistic look of the property, 2) we give a ballpark estimate of rehab costs (we do 40 a year with our GCs o we will get pretty close), 3) we talk through market rent with our property management team, ARV, and potential highest and best use.Ideally you find great investor agents who know their market really well and have a network of resources to provide you with enough confidence to take reasonable action. 

I'd love to help anyone break into the Huntsville Market! 

I have an investor friend who is a very successful wholesaler in a market, (south FL), that is crawling with wholesalers. 

It's a free market. - You will finally get a tenant. 

On my new builds we hit the double cash on cash in certain markets sometimes its only 50%.

Marketing = momentum.

I think our modeling has adapted to market changes over the years, so we've stuck with Excel as we can easily change the parameters to keep it "fresh".
