Without knowing you specific market I am fairly certain no one on this forum will be able to give you an accurate answer. That said I would recommend that you spend a little money and hire a local appraiser as a consultant. Not all appraisers will be willing to do this but there are a number that will. What I would ask this person to do is to take an honest look at your house and it’s value in the current market, what differentiates from the comparables, and if the time and money to complete the proposed implements are worth it in the market.
Remember nearly all landscaping improvements require a grow in period and can actually look worse when completed than before you started. I don’t know how things are in your area, but labor and material availability and project scheduling are experiencing significant delays and having a project in process may actually make your property less desirable. The other potential problem your thoughts on what needs to be done is not what the eventual buyer may want.
You may be better off lowering you price say $50,000 or $75,000 and sell the property as is. Sure it is less money, but the house will be sold saving you the hassles of the proposed project and all of the carrying costs of hanging on to the property during the construction period.
Lastly, spring tends to be the start of the selling season and Interest rates are moving upwards. So you have the most potential buyers and the best rates starting right about now. A major part of the buying decision is the monthly payment and as rates increase so do payments and another increase or two may eliminate some of your potential customers.
Calculate your monthly costs including taxes, insurance, maintenance, utilities, interest (mortgage or loss of investment income) and that will tell you how much more you will have to receive for your house each month to break even. Something I learned a long time ago “many times your first loss is your least loss”. If you get greedy trying to squeeze the last dollar out of the sale, you may end up costing yourself lots of money, time and frustration.
Good luck,
