@Gary F. it really depends on the location of the property and what buyers are doing in the area. In many cases buyers want to do their own updates, so they won't give you anything additional for the "upgrades". On the other hand, if you are in an area where people come in and just move in, there might be some upside, but I think it will be minimal.
Also keep in mind that all of this work you are talking about takes time. Do you have the time to burn to get these things done? Jacking out an existing driveway and putting in pavers is not a small job... If the cracks are minor, I would just leave it. If you have serious cracks with large gaps or it is uneven, then you might want to consider some options, but it sounds like your problems are not big.
I would consider doing the paint job if the current paint is bad or the color is ugly. You will be surprised how much a nice color scheme can increase the value of a SFR and the cost is not that high.
Remember we are still in a sellers market... Ask your agent what he would price the home at in its current condition and what he would price the home at with the changes he suggests.
Yes the agent thinks I’ll make up ROI. HE says buyers are looking for move in ready and nice. Especially since it’s a SFR for families they want to be comfortable and not have to fix up themselves. But you’re definitely right about time. Three large projects might be too much to make the prime summer selling season. Plus I’d like to get to my life after moving
In this market I will just clean it advertise as is. Most home owners do not mind renovate it. Most roofers are so busy they will not meet your August schedule. Go get an estimate and show the buyers the cost.
All these homes will sell it within a price range subtract the repair cost from the market range is what you anticipate to get.
