If rates dropped 1-2% on a $600,000 home, it would cost a buyer $3,400 a month.

Fixed Mortgage does come with closing costs and points upfront which the HELOC does not, except a $95 annual fee. 

Some even offer preferred interest rates as low as 5.75% at no cost to you. 

I am putting in a link to something that may be help, a cost of living comparison calculator (https://www.bankrate.com/real-estate/cost-of-living-calculat...). 

The easiest way to find and connect with wholesalers is either bigger pockets or by googling "sell my house fast in (town name)" although that may cost them a click for google ads.

Variable cost and CapEx are where I see most investors make errors on their Pro Forma.  

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. 

You have to put 5% down vs 3.5% down, rates are usually higher, but if you have strong credit, your PMI cost can be cheaper than that of FHA loans. 

EDUCATE YOURSELF - yes, it will take time, but will lead to a selection that better meets your expectations & avoids potentially costly surprises!

So, we now find most areas where the cost of PM leaves but the general real estate passive investment ROI for the investor hiring property management.
