He threatened me if I'm not paying him he gonna put lien on my property, I've never encounter these thing in my whole life...He seems very cold blood and likes to take his client to court or put lien on the property, looks like he had done these stuff many times in his career...I just don't suggest you to work with him for the below reasons:1.He is never willing to communicate about the project progress and he just notify you that you have to pay for next-phase otherwise he will STOP the work and take all the stuff out2.He will never take responsibility on warranty or the stuff he had done, if you ask, that is all your fault, and you have to pay your own bills3.Finally if nothing of these lightly threaten works, he will say: "I will give you 3 days, if you don't pay me, I will put lien on your property, I will take you to the court"I never done business into this situation in my whole life, but it looks like that's how Robert Mincey makes money and if you work with him, you will probably end up like me with tons of sleepless nights...If there are any chance, in the future I will post my whole experience while working with him.Hope this helps!

In light of this, would lenders see me as a higher risk if I have a history of paying off mortgages early?

If you can focus more on that, then the bottom line profit you will be light years ahead of most flippers. 

After the first go for one with a light rehab.   

You can have a formula to pull the individual property tab income to this master tab.I have my ROTH IRA owned properties with a different colored tab and they are in a separate section on my master tab.

. - New windows, AC ducts, attic insulation, gutters, appliances, fans & lighting, paint, and tile.

The easiest way is to do a BRRRR on light-value add properties.

The light will boost the value to a tenant but it doesnt count as a bedroom legally until it has it.

You need to understand the market, advertise to buyers, show it in the best light, know what to say and what not to say, be skilled at negotiation, understand contracts, and much more.If you don't know how valuable a good agent can be, it's because you've never used one, or they made it look easy because they are skilled.
