I too, have a small lot. My run on 160m started in 2014. I installed an inverted L with 4 elevated radials and worked the 160m contests that winter. After that winter I concentrated on getting to 300 DXCC and DX Marathon QRP and took a hiatus on 160m. I took down the 160m inverted L and put up a 30m delta loop.
As one can see my 160m had a very pronounced lull from the chart below:
The run ended abruptly in the Spring of 2015. I felt I needed more power and a better antenna. More power came in the form of an old Clipperton L that will do KW on 160m. I had put in a brand new set of high voltage capacitors in the power supply. I tested it and found that it will push 1000W with 100W of drive. (See my post in May 2016). I really have not had to push power past about 750W and for the most part gotten away with mostly using the KPA500 since I still had the "old reliable". In January of 2017 I had put up a folded counterpoise (FCP) design espoused by K2AV and W0UCE (SK). It only has a 66 foot folded counterpoise from 174 feet of solid copper wire which takes up very little space. It requires a specially designed isolation transformer. There are many articles on this design on the net.
I did have a good run for a few days in January but it still remains to be seen whether I can keep up this pace. I already see that it will likely slow down. Below is a picture of the installation of the FCP Inverted L. The radiator is 150 feet long and I nailed the SWR without pruning. It is reasonably flat from 1800-1835 with SWR < 2 and then I have to add inductance above 1835. I could remove a few inches and center the dip in the SWR to about 1.825 but fooling with the set-up might do more harm than good since the proximity of the horizontal radiator to ground might change the capacitive coupling. I think I will leave well enough alone. Not a big chore adding inductance through the tuner.
Here is the SWR Curve
