I gave him a bill for the damaged ceiling, he said it was too high and will not pay that amount.

Hi I do have a few rental properties, but I wanted to seek advice on flipping and fixing them.

Seller financing won't have any impact on the potential capital gains that you would face by selling a property, either -- you're still selling a property for the same appreciated amount.

Yet because my house is in a close radius to the beach (only 2.5 miles as the crow flies--the 7 miles is what it takes to a drive out, around, then over the bridge), it seems like PriceLabs is using on-the-beach or walk-to-the-beach properties as comparables, and this may be leading to dynamic prices that are too high.I am not sure exactly how to fix this.

For instance, if getting a normal deposit, put "N/A" and the amount for the security deposit.

With an average response rate of 0.5%-1% for most campaigns, are you hitting enough houses to expect a reasonable amount of calls to your number?

I've seen that typically, 30 year fixed mortgages rates will be roughly the federal funds rate +2% (give or take factoring in other economic conditions). 

My personal opinion is: once the renovation is done, property is rented and generally stabilized, I take out a fixed rate mortgage.  

When you are going to A areas I can understand but b- to c+ areas still working I belive.For example if you buy and fix for 80k and sell for 110k or 120k, why sell?

Passive income won't make you significant amount of money, if it did then where are you actively placing it?
